Liu saw the blank expressions on the faces of the two of them, and instantly understood the problem.

I sighed helplessly in my heart.

These two people didn't see that they had studied physics, so they couldn't understand what they were talking about at all.

While lamenting the benefits of receiving an education, I wondered what to do to make them understand.

I knew that the physics knowledge I talked about in junior high school in Huaxia belonged to the nine-year compulsory learning!

Liu looked up and saw the bamboo pole next to the stone table in the courtyard, which was a little white from the sun, which formed a strong contrast with the yellow-green color on the back of the light.

With an idea, he walked to the cabinet full of finished products, took out an empty brocade box from the cabinet, opened it, tore off the red flannel inside, and walked back to the small table.

Picked up the flashlight on the table, turned on the flashlight, and said to the two, "Look, the color of this light is white, right?"

"Yes!"

The two nodded.

"And now?"

Liu Yiyan covered the red flannel on the lamp port of the strong flashlight, and the light that suddenly shone out was red.

"Red!"

Although the two didn't know what Liu Yiyan was going to do, they still replied.

"Look at the color of the light. ”

Liu Yan slowly lifted the red flannel up, when it was raised, the pillar of light shining on the red flannel, with the red flannel as the dividing line, the red flannel above the red flannel was the red light, and the red flannel below the white light.

"This ......"

Chen Song and Yang Hao didn't know how to answer for a while.

In this case, is the light red or white?

Does this have anything to do with the fact that violets lose their color when exposed to sunlight?

The two looked at Liu with puzzled faces, and they really didn't know what medicine he was selling in his gourd.

Liu glanced at the different colors of light up and down the red flannel, and said: "Only the luminous body has its own fixed color, which is not affected by the reflective color brought by other light and the surrounding environment, and after covering it with red flannel, the light it shines out will become red. ”

After listening to Liu Yiyan's words, Chen Song and Yang Hao finally understood.

As long as it is light, it will have an effect on the color of the object, and when the influence color is too large, the original color of the object will be weakened!

Chen Song asked, "Master Liu, since light can affect objects that don't emit light, can't other jadeite colors also affect it?"

Liu nodded and said, "Yes, as long as the light is strong enough, all objects will obviously feel the difference in color, but the purple in the jade is more likely to be affected!"

"Master, since light can affect the color of violets so easily, wouldn't it be possible to use lights to do tricks?"

Yang Hao's face was excited.

Liu Yiyan did not directly answer Yang Hao's question, but put down the strong flashlight and red flannel, turned around and walked to an iron frame, found a few purple jade rough stones on it, put them on the table, and said to the two: "You guys light up one by one and see!"

Yang Hao stepped forward, picked up a strong flashlight and shone it on the first purple and reddish jade rough.

Under the light, this piece is a reddish-purple jadeite rough, red like a fire cloud dazzling, the color of the whole rough is about to come out, giving people a warm and lively feeling.

Yang Hao looked at it for a while, then lifted the strong flashlight and put it on the second blue-purple jade rough.

This blue-purple jadeite rough is like an iceberg beauty under strong light, giving people a cold and arrogant feeling, but the purple on the rough stone is blue.

The third piece is pink-purple jadeite, the lighting is a whole piece of transparent, ordinary a pink-purple bulb, the light reflected by it, instantly filled the whole room, the pink-purple on it is relatively soft than under natural light, giving people a fresh and elegant romantic atmosphere, this kind of girl pink-purple beauty don't want it!

The fourth violet jadeite rough under the strong light, the purple is rich and pure, it seems to have a kind of rich and graceful spirit, it looks rich and elegant, solemn and rich!

The last piece is completely purple jadeite rough, under the strong light, the purple inside is very viscous, fused together, there is a kind of water overflowing, it is about to flow out of it, the light emitted is full of the temptation of the purple purple, which makes people salivate, it is simply beautiful!

Yang Hao put away the flashlight and said, "Master, with the same light intensity, the colors that appear on these rough stones are too different, but I feel that they are already the most perfect!"

The difference in color between the light and the natural light is too great for these rough stones.

Under the strong light, some have strengthened the purple, while some have weakened the purple, and even some have the purple deviated, but no matter what the situation, it makes people feel that the purple on these rough stones and the corresponding seed water are completely matched and impeccable.

"Of course it's different, their water color has gone to the extreme!"

Liu glanced at the five purple rough stones, remembered the difficult process of obtaining them, and couldn't help but sigh: "These five rough stones represent the top level of the five purple jadeite species, according to the richness and saturation of the color, they are imperial purple, red purple, blue violet, pink violet and violet. ”

Stretching out his hand and brushing them one by one, as if talking to himself: "This piece of reddish-purple jadeite, as the name suggests, is purple reddish jadeite, its color is purple with a red hue, although it is not as strong as royal purple, but the hue is also bright, and the value is second only to the imperial purple." ”

"This piece of blue-purple jadeite is also called eggplant purple jadeite, it belongs to the kind of purple blue, the color has dark purple and light purple, it is the more common type of purple jadeite, the hue is blue, the color changes greatly, from light blue-purple to dark blue-violet can be seen, there is often a gray-blue feeling, this blue-purple jadeite rough is like an iceberg beauty, giving people a cold and arrogant feeling. ”

"The purple of this violet jadeite rough is rich and pure, with high saturation and medium brightness, giving people a kind of rich and graceful spirit, which is the highest quality of violet jadeite, and it is difficult to find one of them in a hundred miles, and this color is almost the color of legend. ”

This piece of pink-purple jadeite is a relatively common purple, it is a piece of excellent pink purple, its water head is very moist, the fleshy jadeite is delicate, it seems to be rich, but it is actually fresh and elegant. ”

"The last piece of imperial purple appeared, in order to distinguish its reddish or bluish tone of violet jadeite, its probability of appearing is almost less than one percent, it can also be said that it is a theoretical color, as its name is as luxurious and rich, its color is strong and pure, high saturation, luster is also very good, like this piece of jadeite rough, needless to say is also extremely rare superb, is a lot of people dream of the best, its collection value is the top level. ”

After Liu finished speaking, he stopped his hand on the last piece of jade rough stone, and looked at the five rough stones with a somewhat confused look.

Yang Hao asked: "Master, isn't it that the light can't make it even better if it's a jade like this that goes to the extreme in all aspects?"

Liu Yiyan pulled back his mind, withdrew the hand that was touching the original stone, and said with a smile: "Yes, everything, if it has been reached to the extreme, it means that one more point and one less point will not work, no matter which side improves again, it will be more than a snake!"

"Master, it belongs to the purple jadeite rough with good water, is it not that this kind of light death will not occur after processing?"

Yang Hao hesitated, but still asked.

"The same, this has to do with the quality of the water, but the main thing is related to the depth of the color, the darker the color, the easier it is to retain the color, the lighter the color, the easier it is to be affected by the light! Just like the famous Zhaoyi Star, that is, the peony stamen weighing 9499 carats, it is a national treasure made of glass violet jadeite as the main stone, according to the raw material estimates, its total value is more than 1 billion Chinese coins, such a masterpiece of ingenuity, will also fade and white!"

Liu Yiyan smiled and continued: " So how much will be affected by the light, purple color will be a little lighter after the light, violet jadeite is a very normal phenomenon to see the light death itself, other colors of jadeite will also see the light death, but the color of violet jadeite is rarely dark, are from medium color to light color, plus its species of water quality is rarely matched with the color, resulting in it will be attenuated more obvious than other colors, ten spring nine wood is said to be violet, most of its texture is a kind of tender flesh coarse, easy to be invaded by external chromogenic ions, so the spring color is the most common variety of violet jadeite。 ”

"Master, will these jade rough stones also have purple attenuation?"

Yang Hao raised his head and asked.

The water color of these jadeite rough stones is already top-notch!

Wouldn't it be a pity if there was also color attenuation!

"Yes, it's just not obvious, or it's a different way to shift the colors in the light!"

Liu Yiyan pointed to the blue-purple jadeite rough and said: This blue-purple is like this, its color will be brighter than the interior in natural light, at this time, seeing the light is not to see the natural light die, but to see the light die, because the natural light has a warm color, and the blue tone on the original stone neutralizes, highlighting the purple, and the light is a cold tone, but aggravates the blue tone on the rough stone, overpowering the purple, making the purple lighter!"

"Is that okay?!"

Yang Hao and Chen Song looked at this blue-purple jade rough and were so surprised that they couldn't close their mouths.

What a pervert, you can still do the opposite!

It's no wonder that when I turned on the light, I found that it didn't look good in natural light, and after the light, it was a bluish tone, giving people a cold and arrogant feeling.

"Yes!"

Liu nodded and said: "The structure of jadeite is ever-changing, what kind of situation will be, not to mention that jadeite itself is the art of light, the color is very sensitive to light, among which purple is particularly prominent, there will be different purple effects in different lights, yellow light is pinkish purple, white light is blue-violet ......"

Stopped, turned his head to Yang Hao and smiled: "This is the secret of purple jadeite to do tricks and feet, and there are many jade merchants in the outside world who are now using this method!"

"Is there really anyone doing it?"

Yang Hao glanced at Liu in surprise.

"In fact, it's not called a trick, it's just a marketing tactic, the purpose is to make the jadeite look more beautiful, and now the hair salon will use pink lights, not to mention selling jadeite?"

Liu Yiyan blinked his eyes and said with a smile: "Of course, it is not excluded that there are unscrupulous merchants who deliberately induce them!"

"Induce? How do they do it?"

Chen Song asked curiously.
