The curiosity of the crowd was aroused by the strange light dispersion experiments, who had never known that light was made up of so many colors.

Or is it only artificial light that has such properties?

"Whether it's this light or sunlight, of course it's the same, it's all compound light." Lynn explained to the curious Elok and the others.

To put it bluntly, the refractive index of light of different colors in the glass is different, so when passing through the prism, the light of various colors is deviated from one direction, which constitutes a gradient spectrum......

The wizard apprentices listened thoughtfully, and Lynn's explanation was very easy to understand, even Raeder and others, who didn't know magic, could barely understand it.

"Wait, I think I've seen something like this......" Hamm said sharply, staring at the rainbow light reflected from the prism, with a thoughtful look on his face. Yes, it's like ...... Rainbow like? ”

As soon as Hamm said this, more and more people reacted, although the rainbow phenomenon is not very common, but many people have seen it.

"Is there a mirror in the sky?" Lydia asked, holding her hand aloft.

This time, without waiting for Lynn to reply, Philip explained.

"It's supposed to be the refraction and reflection of water, right?"

The air is filled with a large amount of water vapor, which every wizard knows very well, and the surface of the water also has the ability to refract and reflect light, so Philip instantly figured out how it works.

"Not bad!" Lynn nodded, then handed the prism in her hand to Lydia's hand. "As for the other properties of light, I will leave it to you to explore."

Lydia was very excited to take the prism and put it under the light and rotate continuously, and the light in the prism kept flowing and reflecting, changing the size and color.

Elok and the others looked at Lynn with blank eyes, and the Dean gave the only Mitsubishi mirror to Lydia, so what should they do?

Don't be so eccentric!

"It's not hard to get glass, you can also make formulas, I taught it in chemistry class, why don't you just make one yourself if you want? Studying the spectrum of the sun is also your homework assignment! Lynn shrugged her shoulders and spoke freely.

As soon as they heard the assignment, Ellock's faces suddenly drooped, and they tried to remember the chemistry lesson that Lynn had given them some time ago.

What is the main composition of glass...... Like silica?

"I heard that there are many wizards in Greenriel City who are studying the mysteries of light, and even the Speaker is very interested, and there are many opponents in them!" Lynn added.

Although the Wizarding Lands has been busy with war lately, the Council still places a strong emphasis on academic research, which is the foundation of all magical power.

As glass became more popular, more and more wizards discovered the use of this thing in research, such as the simplest concave and convex mirrors, which can make things bigger or smaller in their own eyes.

This means that wizards can not only rely on magic to perceive things, but can also intuitively see the microcosm of the world with the naked eye!

Lynn has no doubt that after this war, the 'magic' theory of the entire wizarding land will usher in a wave of leapfrog development!

When they heard that there were already many wizards, and even the legendary Speaker was studying this, the apprentices suddenly felt that they had no hope.

Lydia, on the other hand, was thinking about how to get a little more theoretical knowledge from the dean, which was much faster than doing research on her own......

"By the way, Professor Philip, how did you study that railgun?" Lynn suddenly remembered this, turned her head to look at a few people, and asked.

"The principle has been figured out, and the model has been figured out, but it is somewhat unsatisfactory in terms of power, and it can only launch a 100-gram projectile at a speed of 100 meters per second." Philip said helplessly.

The generator they made was fine for lighting a light bulb, but it was a little too weak for a railgun, and if it wasn't strong enough power, it wouldn't be as good as a gun.

Lynn was not surprised by this, the generator needed to be improved for at least several generations to meet the needs of the electromagnetic gun, and after thinking about it, he had a basket of black stones and an engraving plate brought over.

"This is the Lightning Stone and several magic runes that represent electromagnetism, you can study how to use them!" Lynn explained.

Since the old way doesn't work, it's better to think differently!

These two things are the research results of Anthony for most of his life, and the lightning stone is like a natural battery, or the kind of super power, and these electromagnetic runes are the key to the magic conversion of electricity!

When Philip and the others heard this, their eyes lit up.

In this way, they can store all the excess electricity on weekdays, and try to export it when they need to use the electromagnetic cannon, and even directly use the lightning stone as the material of the guide rail, and plate a layer of mythril on the outside, and engrave electromagnetic runes......

In just a few seconds, Philip had many ways to improve the electromagnetic cannon in his mind, and many of the difficulties that had plagued him in the past were directly solved!

Thinking of this, Philip hurriedly said goodbye and pulled a few colleagues to carry a basket of lightning stones to do research.

The huge light bulb was lit all night inside the castle, both to test the sample and to be intentional on Lynn's part.

So much so that early the next morning, rumors of electric lights spread rapidly throughout the county, and then spread more and more outrageously, and some people swore that they had seen the wizard fly into the sky, catch lightning and a huge rainbow from the clouds, and put them into a ball and a gem!

Instead of bluntly defending these rumors, Lynn assigned a new task to the musket team that went out to train every day, that is, to use the water mist method to create an artificial rainbow in the square, and gave this method to every curious child who wanted to learn.

The change of concept is often subtle, and Lynn is ready to let these people know that wizards are not terrible, and the knowledge they spread is not a trap for the devil, but an explanation of the laws of the operation of everything, even ordinary people can understand and use it!

The next question was how to solve their last obstacle to the kingdom – the Cardinal of the Church, Ann Sulfe!
