With the appearance of Mavericks, Xu Yun seemed to 'sense' something.
There were three parts of shame, three parts of surprise and four parts of panic on his face, and he put away his glasses in a hurry:
"I'm sorry, Mr. Isaac, I accidentally forgot the time. Now I will..."
Before he could finish speaking, Mavericks interrupted him:
"what is that?"
"ah?"
Xu Yun blinked, waved his glasses, and pretended to be stupid:
"As you can see, this is a pair of glasses."
Mavericks shook his head at him and said:
"Of course I know these are glasses. They were a masterpiece of Sir Francis Bacon in the mid-13th century. My mentor, Mr. Rowan, had a pair of expensive custom-made lenses.
What I’m asking is…what is that seven-colored light on the wall?”
When Xu Yun heard this, an expression of relief appeared on his face just right, and his acting skills were simply inferior to some young talents:
"Oh, you said that seven-color light is a dispersion phenomenon."
"Dispersion phenomenon?"
Xu Yun nodded and explained:
"In a faraway eastern country, there is a knight named Han Li who has extraordinary talent.
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 violet. He called this phenomenon dispersion."
As soon as Xu Yun said these words, Xiao Niu was stunned for a moment, and then his pupils suddenly shrank!
Friends who know optics should all know this.
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 what a coincidence.
Mavericks did the prism experiment on January 14, 1666, only three months ago!
According to Maverick's description in "Optics", his curiosity about light began in mid-June 1665.
At that time, when he was studying the telescope lent to him by Stoker, he suddenly discovered the colors revealed in the distorted images, and thus began his 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 carefully 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, please demonstrate again...well, I'll give you free meals for the day."
Seeing that the fish had taken the bait, Xu Yun had an undetectable smile on his lips and followed the instructions obediently.
I saw him pointing the thickest edge of his glasses towards the sun, adjusting it to a subtle angle.
After a while.
A small cluster of colorful spectra was projected into the shadows again.
Generally speaking, there are two main methods of operating dispersion experiments:
One is the mirror and water, and the other is the prism.
However, if the power of your glasses is high enough, the edges of the glasses can also temporarily achieve dispersion effects.
Because the myopia lens is a concave lens, the left and right sides are thicker, especially for high-number lenses, and the optical properties will be like prisms.
When light hits the lens, the refractive index of each colored light is different, which disperses the various colored lights in the light source, and then enters your eyes. This is a rainbow.
This is also the reason why some people experience color separation when they see the edges or contours of objects in the edge area of their lenses - the theoretical basis is the dispersion of light.
What, what are the technical factors you ask?
Of course it's because the optician's skills are poor...
"Red, orange, yellow, green, blue... Is this cyan? Green, purple, God..."
Seeing the sun's rays dispersed in seven colors under the refraction of the lenses, Maverick's lips trembled with excitement:
As mentioned before, Maverick is a staunch believer, so he firmly believes that there must be some code left by the Creator hidden in everything in the world, reflecting the truth of the world.
And the seven-color light that has undergone dispersion... obviously meets this condition.
Then he suddenly turned his head and stared at Xu Yun:
"Fat Fish, 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 prompt box suddenly appeared in front of him again.
There is no text on the prompt box, only a yellow exclamation mark flashing.
It is clear.
Due to certain 'rules', Xu Yun's spoilers for Mavericks can only be limited to a certain range, or should be done gradually and gradually.
But if you think about it carefully, this is normal.
Otherwise, wouldn’t Xu Yun just tell Mavericks the vector formula of F=-(GMm/r^3)r and be done with it?
So Xu Yun thought for a while and said:
"Mr. Isaac, Sir Han Li only discovered the dispersion phenomenon of light, but did not explain much about its principle.
After all, this was just an insignificant discovery in his magnificent life.
Later, Sir Han Li accidentally disappeared during an adventure and has not been heard from since.
But before his disappearance, Sir, he once mentioned something related to the phenomenon of dispersion."
Mavericks immediately became interested and asked:
"What words?"
Xu Yun paused for a few seconds and said tentatively:
"He said...according to his guess, the main reason why sunlight will appear dispersion may be that the characteristics of each color of light are different.
It's like a school of countless fish. To the naked eye, it looks like a huge group of fish, with an incalculable number.
But if you use filters with different pore sizes to filter, you can separate big fish and small fish.
If we install more filters, we can separate more fish and even fry.
The same may be true for the dispersion of light.
Maybe their ‘sizes’ are different, so after passing through some unknown filter, they will show colorful light.”
Mavericks nodded thoughtfully, pondered for tens of seconds, and said:
"I seem to understand, but Feiyu, I have a question to ask you."
"what is the problem?"
Mavericks raised his eyelids and glanced at him and said:
"According to what you said, there may be big fish or fry in the fish school. This is a category issue within the framework of fish.
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 spread of light actually requires a certain environment, or conditions?"
Xu Yun: "......"
Yaoyaoling, I want to report that someone is cheating here!
