Black friends who are often black are afraid of light, but I think this is too broad. Light, what is light? The electromagnetic spectrum visible to human eyes.
As a student who is not in Xiong Ying senior high school, what I know about the light we can see or can't see is influenced by the intensity (amplitude), wavelength (or frequency) and purity of light. That is, the three elements of light are shown in the following figure, but here I don't consider the influence of the purity of light on it, only consider that the light in wave-particle duality propagates in the form of waves.
Look at the light intensity first.
Scene 1:
Invariants: sunshine, continuous darkness, the site of sports sacrifice.
Variable: Bakugo Katsuki's hand light bomb (flash bomb)
Process: Before Bakugo Katsuki's hand flare was released, under the condition of exposure, friends in the dark night had high morale. When the violent brother's hand is released, in the case of exposure, the night friend is directly suppressed, and there is almost no strength to fight back, and often surreptitiously gives up.
Process analysis: Because Bakugo Katsuki's hand photoelasticity can enhance the light intensity, when the sun shines, the light intensity is higher, and the friends in the dark night still have fighting spirit. However, after adding Bakugo Katsuki's hand photoelastic to enhance the light intensity, the fighting capacity of night friends is obviously reduced, so too high light intensity can suppress night friends.
About the color of light.
Scenario 2:
Constant: the dark friends are in a state of release, and the intensity of sunlight.
Variables: the time of headscarf competition, polychromatic light (that is, the visible part of sunlight)
Process: From the beginning of the game to the end of the game, under the condition of no obvious change in sunshine intensity, the dark friends are always in a state of release, and their fighting spirit is always high.
Process analysis: About half of the electromagnetic spectrum of sunlight is in the short-wave range of visible light, the other half is in the near-infrared part, and there are some ultraviolet rays in the spectrum. (Excerpted from Baidu Encyclopedia)
After a period of continuous exposure to the sun, the dark friends have not changed significantly.
It shows that under the condition of constant light intensity, polychromatic light (that is, the visible part of sunlight) has little influence on dark friends, so the main influence is not the color of light.
Based on the above two scenarios, it can be concluded that with the increase of light intensity, the inhibition on dark friends is enhanced, that is, inhibition, darkness is not afraid of light. So the light intensity is known, how sensitive is it? Obviously, when Bakugo Katsuki ran across the dark side of the runaway with a flare, and Todoroki Shoto was on fire, his dark friend was restrained by the high-intensity light in a short time. All the above are personal opinions.
