Chapter 192 The principle of looking through the mirror
The whole place was boiling.
"What happened? How did Gengar turn into a black bear?"
"Did my eyes get blurred?"
"Why is this happening?"
"What happened?"
Everyone was shocked to find that the originally standing black bear had turned into Li Ran holding a single scabbard.
"Sword!" The crisp sword cry sounded.
This time, people heard rampant emotions.
Li Ran looked at the stunned referee and said, "It's time to announce the verdict."
The referee rubbed his eyes, looked at the confused Circle Bear player and the Black Bear player who lost his intuition, and then announced with a stumbling voice, "Gengar player wins."
"Hey~~Here, I didn't understand the game. Why did the Gengar player and the Black Bear player suddenly switch?" The commentator looked confused.
So did the audience.
"This..." Professor Zhang thought for a long time and suddenly slammed the table.
"I understand, I understand!" Professor Zhang suddenly exclaimed.
"Hey? What's Professor Zhang's opinion?" the commentator became energetic.
Here comes the role of special guests.
Special guests can often use the knowledge they have learned to explain the points that most viewers are confused about.
"It depends on your performance." The commentator gave Professor Zhang a look.
"I want to see if ivory can spit out from the dog's mouth." Li Ran's fans are waiting to see.
Professor Zhang has always been very unfavorable to Li Ran.
I was slapped in the face time and time again, but I never tired of it.
Putting this aside, Professor Zhang's own qualifications are quite good.
Distinguished Professor of Spirituality at China First University.
It's impossible without two brushes.
Even Li Ran, who had already taken a break, couldn't help but look at the screen, wanting to see how Professor Zhang analyzed the principle of the One-Sword Scabbard Mirror Flowers and Water Moon.
Professor Zhang cleared his throat and said slowly: "First of all, let's understand it literally."
"Flowers in the mirror, the moon in the water, the flowers in the mirror, and the moon in the water look beautiful, but they are all illusory. They are all virtual images formed by the reflection of light in a plane mirror (mirror surface, water surface)."
"The principle is that the image of the moon is formed by a plane mirror. The image of the moon passes through the water, and the flowers are reflected into the human eye through the reflection of the mirror. The human eye sees the water and flowers as images in them according to the extension of the reflected light."
"I believe everyone has basically expected this."
"I'm going to talk about a mirage here."
"In the desert, people sometimes see oasis. Hungry and thirsty, they muster up all their strength and rush towards the oasis. But no matter how fast they run, the distance to the oasis never shrinks. In the end, they die due to lack of water.
In the desert."
"Mirages are easy to occur in the desert in summer because the sun is blazing during the day and the sand is scorched. Because the specific heat capacity of the sand is small, the temperature rises very quickly. The temperature of the lower air near the sand rises very high, while the temperature of the upper air remains very low.
This forms an abnormal distribution of air temperature. Due to thermal expansion and contraction, the hot air in the lower layer close to the sand is less dense and the cold air in the upper layer is denser."
"In this way, the refractive index of the air is smaller in the lower layer and larger in the upper layer. When the light reflected from a higher object in the distance is continuously refracted from the denser air in the upper layer into the sparser air in the lower layer, its incident angle gradually increases until it is equal to
Total reflection occurs at the critical angle."
"80% to 90% of our human senses rely on vision. The objects that our eyes can see are images produced by refraction of different media. This also shows that when the brain processes this huge and complex image data
, it is very likely that some data will be lost, which will cause the image you see to be distorted or even false."
After a series of popular science lectures by Professor Zhang, the audience seemed to understand.
"So Professor Zhang, do you mean that the single sword scabbard uses optical reflection to cause us to hallucinate?" The commentator couldn't help but interjected.
Professor Zhang shook his head and said mysteriously: "Yes, and no."
When everyone was puzzled, Professor Zhang explained: "If you rely solely on optics, you will definitely not be able to explain this. After all, the viewers in the live broadcast room have also seen illusions."
Everyone nodded thoughtfully.
"So, first of all, I want to introduce you to the senses of seeing and feeling an object."
"Humans have five senses, which are: shape, sound, smell, taste, and touch, that is, the five sense organs of human beings: vision, hearing, smell, taste, and touch."
"As I said before, our vision is biased due to optics, but optics alone are definitely not enough to explain the occurrence of hallucinations, so I want to mention sound here." Professor Zhang explained in great detail, just like in class.
"Sound?" The commentator was surprised, "But the scabbard of the single sword didn't seem to make a sound. Could it be!" The commentator was surprised.
He sounded the constant sword cry from the scabbard of his single sword.
"Not bad." Professor Zhang nodded with satisfaction, with a teachable look on his face.
"Sound is produced by the vibration of objects. It can propagate through media."
"In other words, sound is produced by different vibration frequencies."
"Therefore, general sound always contains a certain frequency range. The frequency range of sound that can be heard by the human ear is between 20 and 20,000 Hz. Fluctuations above this range are called ultrasonic waves, while those below this range
It’s called infrasound. And animals such as dogs and bats can hear sounds up to 160,000 hertz.”
"The scabbard of the single sword probably emits sound waves other than the sound of the sword. Although we cannot hear these sound waves, they will have an impact on us."
"Under the influence of sound and vision, we all have hallucinations." After Professor Zhang finished speaking, he breathed a sigh of relief.
There was a proud look in his eyes.
This is the expertise of a distinguished professor at one of the best universities in Kanto.
Everyone was impressed.
"As expected of Professor Zhang, I really learned a lot this time." The commentator looked convinced.
The barrage also filled the screen with 666.
Professor Zhang smiled slightly and said: "I have to say that Gengar players are really good at training elves. Whether it is Ghost Stone, Mimikyu or Snow Demon Girl, they have all trained a new idea. I believe that after this game
, trainers will study a new genre, illusion flow."
"This time Gengar won the game cleanly again. Professor Zhang, you made a mistake in your prediction again. What do you think?" the commentator asked with a smirk on his face.
The commentator's sudden attack left him at a loss.
He sorted out his thoughts and said: "I have to say that Gengar player's new elves do have the advantage of unknown information. Although the ability of Mirror Flower and Water Moon is powerful, it is not difficult to restrain it. I believe that Gengar player will have a better future in the game.
It will be more difficult.”
"Okay, thank you Professor Zhang, see you next time."
Applause rang out, and the 90th floor of the wild fighting competition ended.
