After Jeffrey spoke, the apprentices immediately got to work.

With the help of magic, it's easy to make a simple modification to the bezel, and it only takes a few minutes to complete.

The bezel changed from one hole to two holes, and its shape was changed from round to square.

When a powerful beam of light flew out of the transmitter and pierced through two extremely small gaps, the faces of everyone present showed a look of astonishment.

Because there were nine relatively clear rectangular spots on the black wall behind the hole, the middle spot was the brightest, and the brightness of the spots on the other two sides decreased in turn.

"How can there be so many light spots?"

The apprentice who proposed just now was stunned in place, if the light really traveled in a straight line, then after a beam of light passed through two holes at the same time, there should only be two corresponding stripes of light in the same shape as the holes on the wall.

Even if the light is refracted after it hits an object, it shouldn't be such a strange phenomenon - not to mention that the brightest spot is actually located in the center of the two holes, which is completely unreasonable.

This discovery also surprised Jeffrey, who was already vaguely aware of something, but couldn't think of the key point.

"It's like a ripple ......of water," muttered a short wizard beside him.

Jeffrey was stunned for a moment, then turned his head, tugged at the wizard's collar, and asked excitedly. "Water waves? What water waves? ”

The short wizard was startled by Jeffrey's sudden agitation and stammered in response. "It's the ripples of water, teacher......"

"Show me the water waves you just talked about...... Right now! Jeffrey let go of the wizard, dragged a basin of water over the table with the [Mage's Hand], and said excitedly.

The short wizard did not dare to slack off, took a two-hole baffle from the laboratory, put it in the basin, and left it for a few minutes, until the water in the basin was completely calm, and then stretched out his hand to point it on the water.

"It's like this!"

Under the gaze of everyone, the water waves spread in all directions from the center of the fingers, and soon touched the gap in the baffle.

After the vibrating water waves passed through the gap, they immediately split into two new ripples and began to spread inward in a semi-circular shape centered on the gap.

Due to the close proximity of the two gaps, the resulting water waves quickly collide and begin to interfere, cancel out, or merge with each other.

"It's the crests and the troughs...... So it was, so it was! Jeffrey understood the moment he saw the water waves, and his face suddenly showed a look of extreme surprise, no wonder he had a sense of familiarity just now, because this was very similar to the ripples produced by using force field magic to stir time and space.

At this moment, he seemed to have seen a corona medal beckoning to him!

"Teacher, what the hell is going on?" Several of the apprentices beside him had confused expressions on their faces, they didn't understand at all, and they didn't quite understand why Jeffrey was so excited.

The excitement that welled up in Jeffrey's heart was irrepressible, and he immediately explained it to the apprentices. "You can take the ripples spread on the surface of the water as light, and that's easy to understand......"

The water waves will stir up ripples on the calm surface of the lake.

Some places will be uplifted, for the crests, and in some places it will be concave, for the troughs.

If two ripples of equal intensity appear at the same time, as just now, they will interfere with each other when they meet.

When the crests of the two ripples meet, the interference waves generated become stronger than before, and when the troughs meet, the water surface will sink deeper due to the superposition of the two troughs.

In addition, there is another situation where when the crest of one wave meets the trough of another wave, the two cancel each other out.

The same is true of light, when a beam of light passes through two cracks, it will also interfere with each other, so it will produce a strange scene of constantly alternating bright and dark light.

Where it's bright, it's the crest, and where it's dark, it's the trough......

Under Geoffrey's explanation, the apprentices hurriedly looked at the water waves, and soon found that after the two water waves collided, the place where the crest of the wave appeared was exactly the direction where the light spot was lit up before, and the two were almost identical!

"So the scattering and reflection of light is also explained, you see those water waves, after they collide with an object, the force is weakened a part, and then it bounces back......"

The more Jeffrey talked, the more he felt that his theory of light fluctuations was simply seamless, and could explain every natural phenomenon of light.

"Therefore, light is by no means composed of tiny light elements, its essence is a wave, just like the ripples produced by agitating space and magnetic fields, it is a continuous and inseparable existence!" Jeffrey summed it up categorically.

This is definitely enough to shock the entire wizarding world and decipher the nature of light!

The wizards and apprentices gathered around Jeffrey were equally excited.

One can imagine how stormy it would have been for them to come up with this theory at an academic symposium three months later, and their teacher Jeffrey would undoubtedly be rewarded with a Corona Medal, and their auxiliaries might have been rewarded with a Morning Star Medal.

What a great honor!

Just when the wizards of the school were happily patting their ass, some people also made a worried suggestion. "Teacher, do you want to release some of the results first, I heard that there are many schools of thought that are studying optics, and since we can discover this phenomenon, others may not be unexpected."

Hearing this, Jeffrey immediately became vigilant and hurriedly spoke. "That's right, I'll start the manuscript now, you can sort out the research notes of these days as soon as possible, and it's best to sort out the paper before noon."

"And go and help me find the editor of the Magic Daily, Rohr, I remember that he stopped in the City of Fire Oil recently, if he is fast enough, he may be able to catch up with the Magic Daily published tonight!" Jeffrey spoke at great speed.

This experiment is actually not difficult to do, and the water wave theory is not so difficult to think, Jeffrey knows very well that the reason why he was the first discoverer is entirely due to the fact that he stayed in the rear to refine deuterium and tritium elements, and has plenty of time to engage in academic research.

Now that the war against the empire is coming to an end, everyone's time is free, and if we wait until the academic seminar in three months' time, who knows if anyone will cut off the beard.

In short, release some of the research results first, occupy a position, and never let others snatch this glory first!

Jeffrey worked hard to write, spent several hours of hard work, and successfully finished the paper before noon, and his mood suddenly improved to the extreme, and he gave each of the wizards in the laboratory ten magic gold coins as an early reward!

As for the few wizards who reminded him and gave him inspiration, Jeffrey patted his chest and promised that he would definitely make sure they got a Morning Star medal!

"Anthony, they're probably still studying the changes in the magnetic and electric fields, right?" Jeffrey thought proudly that there were three great wizards over there, and until now he had not been able to figure out the electromagnetic field thoroughly, so he had figured out the nature of light first.

Jeffrey couldn't wait to see what kind of expression they would look at after today's Magic Daily was released.

At the same time, in the city of oil, the great wizard Anthony and the others who were thinking about Jeffrey were pacing anxiously in the laboratory, staring at the four exquisite formulas in front of them from time to time, frowning and pondering.

These formulas are none other than Maxwell's equations that Lynn wrote down in the small universe!

At the beginning, Anthony felt that these four formulas were extremely profound, and after in-depth research, he was even more surprised to find that this is simply the bible of thunder magic!

Dismantling each formula, its equation is enough to cover several pages, and their research and experiments on electric and magnetic fields are enough to prove the accuracy of these equations.

In the words of some Thunder Wizards - the truth is coming to the page in a wonderful way!

Now they are looking at the speed of lightning propagation in different media.

Like light, the speed of thunder is also extremely fast, and the speed of propagation in the air can even reach tens of thousands of kilometers per second!

But that's clearly not the limit!

After experimenting with dozens of different substances, Anthony discovered that thunder travels extremely fast on conductors, and in order to conduct an accurate experiment, they made several conductors made of different materials up to ten kilometers long, and prepared to demonstrate how fast they were.

This experiment should be able to bear fruit today!

Just as Anthony's mood became more and more impatient, the closed laboratory was finally opened, and dozens of thunder wizards rushed in, one of them said happily.

"The experiment has been measured, Master Anthony."

"How fast does it travel?" Before Anthony could speak, the thunder wizards on the side eagerly asked.

"That's 299,000 kilometers per second!" The man replied.

"Twenty-nine thousand kilometers......," Anthony muttered, how did this speed sound so familiar.

"Are you sure you're not mistaken? Isn't that about the speed of light? Fura the witch said in confusion.

"Of course I'm not mistaken, we've tested it hundreds of times!" The Great Wizard Sanchez rolled his eyes, the current travels at the same speed in each conductor, and it is due to the problem of resistance that the current transmitted in the end is of different intensity.

In order to ensure its accuracy, Sanchez even took it upon himself to judge the moment the current arrives with the great wizard's excellent perception and computing power.

Dozens of times in a row, he was almost electronumized, so he was extremely sure that this value was not mistaken!

"But...... How could it be such a coincidence? The wizards present looked at each other.

Last time, they relied on the rotation of the gears to test the speed of light at 299,520 kilometers per second, and the difference between the two was negligible, and it could even be said that it was exactly the same, but the speed was too fast and exceeded their reaction ability, so there would be some slight errors during the test.

Anthony also does not believe that this is just a coincidence, and there must be a deeper relationship between the two.

He was already aware of this when he was studying Maxwell's equations.

Suddenly, as if he had thought of something, Anthony suddenly pointed to Maxwell's equations on the table and shouted excitedly. "I see...... Light is electricity, light is electricity! ”

"Light is electricity?" Sanchez couldn't help frowning, although the current speed in the conductor is similar to that of light, but you can't draw such an arbitrary conclusion, right?

You must know that the speed of thunder in the air is far inferior to light, and for example, they can barely sense electricity, but they can't sense the light element at all!

Anthony explained with great fanaticism. "Listen to me, light may be another form of electricity, and the two are like the relationship between a magnetic field and an electric field!"

"It's like the electric lights all over the city of oil, after the electricity enters the wick, it is consumed in the form of light, or the electricity is converted into light and emitted!"

"If my guess is correct, electricity can be converted into light, and the gathered beam of light must also be converted into electricity!" Anthony slapped the table excitedly.

"Quick, let's start the experiment now!"

Hundreds of Thunder Wizards immediately got busy, and after a full night, trying countless materials, they managed to create a rudimentary solar installation!

Just as Anthony thought, after the beam hit the device, it was continuously converted into electricity!

Witnessing the successful start of the motor, the entire laboratory suddenly erupted in violent cheers and applause.

"Teacher, you are right, light is electricity, electricity is light!" Fura is also honored, it seems that they have won this corona medal that penetrates the essence of light!

Sanchez added. "I dare say that light is mostly more tiny electrons, and lightning is like those radioactive elements, after being excited, it will continuously throw its own energy in all directions until it is exhausted."

"What a brilliant idea, it seems that it won't be long before we can find the light particles, or even smaller electric elements!" Anthony said with appreciative remarks.

This discovery is sure to detonate the entire wizarding world, and their names will surely be etched in the history of magic!

However, just when everyone was rejoicing, the door of the laboratory was slammed open.

Anthony turned his head rather dissatisfied, and found that it was his other disciple who pushed the door in, Cagal.

Cagar had a few pages of newspaper in his hand, and as he hurried through the door, he gasped. "Teacher, take a look at today's Magic Daily, said Lord Archwizard Jeffrey...... He has succeeded in deciphering the nature of light! ”
