Into Unscientific

  Chapter 22 is nothing short of eternal obsession.

   Outside the garden room.

  With the appearance of Mavericks, Xu Yun seemed to have 'sensed' something.

  There were three points of shame, three points of surprise, and four points of panic on his face, and he hurriedly put away his glasses:

   "I'm sorry, Mr. Newton, I accidentally forgot the time, and now I will."

   Before he could finish speaking, Maverick interrupted him:

"what is that?"

"what?"

  Xu Yun blinked, waved his glasses, and pretended to be stupid:

   "As you can see, this is a pair of glasses."

   Maverick shook his head at him and said:

  "Of course I know that these are glasses, the masterpiece of Sir Bacon in the mid-13th century, and my mentor, Mr. Rowan, has a pair of high-priced custom-made lenses.

   What I'm asking is what is that seven-color light on the wall? "

  Xu Yun heard the words, a sense of relief appeared on his face just right, and his acting skills simply beat some fresh meat:

   "Oh, the seven-color light you mentioned is a kind of dispersion phenomenon."

   "Dispersion?"

  Xu Yun nodded and explained:

   "In a distant eastern country, there is a knight named Han Li, who is extremely talented.

  He discovered that after sunlight is refracted by a prism, it will be refracted and dispersed into seven main colors of colored light: red, orange, yellow, green, blue, indigo, and purple. He called this phenomenon dispersion phenomenon. "

  As soon as Xu Yun said this, Maverick was taken aback for a moment, and then his pupils shrank suddenly!

   Friends who understand optics should know it.

   For a long time, people have always believed that white is the purest color, and white light is the purest light.

   It wasn't until the 17th century that someone used a prism to disperse sunlight, and the secret of color was revealed.

   And this person is

   Newton!

   And quite coincidentally.

   Mavericks did the prism experiment on January 14, 1666, which is only three months from now!

  According to Maverick's description in the book "Optics", his curiosity about light began in mid-June 1665.

  At that time, when he was studying the telescope that Stoke lent him, he suddenly discovered the color revealed in the distorted image, and thus began the study of light.

  In the past few days, Mavericks has tried convex lenses of various sizes, but still has not discovered the mystery of natural light.

  At the same time, due to the problem of binomial simplification, he temporarily put this idea aside, and planned to study it when he had time.

   The result was unexpected.

  In Xu Yun, a visitor from the east, he actually saw the dispersion of light so dramatically, or

  The truth about light?

   Then he took a deep breath and said to Xu Yun:

   "Fat fish, demonstrate again. Well, I will give you a day's meal for free."

  Seeing that the fish had already taken the bait, Xu Yun raised a slight smile on his mouth, and obeyed obediently with his hands.

  I saw that he turned the thickest edge of the glasses to the sun and adjusted a subtle angle.

   After a while.

  A small cluster of colorful spectrums is projected into the shadows again.

  Generally speaking, there are two main modes of operation for dispersion experiments:

  One is the mirror and water, and the other is the prism.

  However, if your glasses are high enough, the edge of the glasses can also temporarily achieve the dispersion effect.

  Because the myopia lens is a concave lens, the left and right sides are relatively thick, especially the high-number lens, and the optical characteristics at this time will have the nature of a prism.

  When the light hits the lens, the refractive index of each color light is different, which disperses the various color lights in the light source, and then enters your eyes. This is a rainbow.

  This is why some people see color separation when they see the edge or contour of an object in the edge area of ​​the lens—the theoretical basis is the dispersion of light.

  What, you ask what are the technical factors?

  Of course the optician’s skills are poor.

   "Red, orange, yellow, green, blue, this is cyan, right? Cyan, purple, God"

  Seeing the colorful dispersion of sunlight under the refraction of the lens, Maverick’s excited lips were trembling:

  As mentioned before, Maverick is a firm believer, so he firmly believes that there must be some codes left by the Creator in all things in the world, reflecting the truth of the world.

  The dispersed seven-color light obviously meets this condition.

   Then he turned his head suddenly and stared at Xu Yun:

   "Fat Yu, did Sir Han Li explain this phenomenon?"

  Xu Yun opened his mouth, and was about to tell the cause and effect of the dispersion phenomenon, but found that he could not make a sound no matter what.

   At the same time, a reminder box suddenly appeared in front of his eyes again.

  There is no text on the prompt box, only a yellow exclamation mark is flashing.

It is clear.

  Due to certain 'rules', Xu Yun's spoilers about Mavericks can only be limited to a certain range, or in other words, it must be done gradually.

   But thinking about it carefully, this is normal.

  Otherwise, Xu Yun would just tell Mavericks the vector formula of F=-(GMm/r^3)r and it would be over?

  So Xu Yun thought for a while and said:

  "Mr. Newton, Sir Han Li only discovered the dispersion phenomenon of light, but he didn't explain much about its principle.

   After all, this is just an insignificant discovery in his magnificent life.

   Later, Sir Han Li accidentally disappeared during an adventure, and there has been no news of it.

  However, before his disappearance, Jazz once mentioned a word related to the phenomenon of dispersion. "

   Maverick immediately became interested and asked:

   "What words?"

  Xu Yun paused for a few seconds, then tentatively said:

  " He said. According to his guess, sunlight will be dispersed, and the main reason may be that the characteristics of each color of light itself are different.

   This is like a school of fish composed of countless fish. It looks like a large school of black to the naked eye, and the number is unknown.

  But if you use filters with different pore sizes to filter, you can separate big fish from small fish.

  If more filters are installed, we can separate more fish and even fry.

  The same may be true for the dispersion of light.

  Maybe their own 'size' is different, so after passing through some unknown filter, the colorful light will appear. "

   Maverick nodded thoughtfully, pondered for tens of seconds, and said:

   "I seem to understand, but Fat Fish, I have a question to ask you."

"what is the problem?"

   Maverick raised his eyelids to look at him, and said:

   "According to what you said, there may be big fish in the fish school, and there may also be fry, which belongs to the category of fish within the framework.

  But for fish schools to survive, they must have a suitable external water environment, right?

  For example, in the sea, lakes, rivers, etc., but obviously not on land and in the sky.

   Does that mean

  The propagation of light actually requires a certain environment, or conditions? "

  Xu Yun: "."

  Yaoyaoling, I want to report that someone is cheating here!
