Yes, the skin cell is much longer than the wavelength of visible light. The wavelength of visible light is in the range of hundreds of nanometers. Skin cells are much larger.
Too much exposure to visible light can cause damage to your retina.
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
visible light
It is electromagnetic radiation, which is the same in composition as visible light but has a much higher frequency/shorter wavelength, and will do damage to any biological material it passes through. Both travel at the same speed ('velocity of light') but gamma radiation can penetrate material opaque to visible light.

All of it. White light is the blend of all visible colors.
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
Gamma rays are of higher energy and much much shorter wavelength than visible light.

They are the blue and red frequencies of visible light. Green is not absorbed much
its hey
it is 70% so that is the answer of how much light on the earth surface
White does not absorb light - it reflects all visible light waves, while black absorbs all visible light and reflects nothing.
X-rays are electromagnetic waves - that is, of the same nature as visible light. However, their frequency and therefore their energy are much higher than that of visible light, while their wavelength is much lower.
