Question about Photoelectric Effect

Where does your assumption that our skin releases electrons come from?

The frequency of Blue light can strong enough to hit electrons remove from gold leaf electroscope, but not the red light.  Our skin are on neutral states, under blue light, electrons are easily removed from any molecule atom and create free radicals, so people are easier to get skin caner under blue light during  noon period as comparing during sunrise and sunset with less blue light.

Would it be correct? Do you have any suggestions?
Thank you very much for any suggestions (^v^)


Gold Leaf electroscope


What Is A Free Radical?

Can you make sense of this?



Light penetration in the skin

(attenuation down to 1% occurs for light wavelengths of 250-280 nm at around 40 μm depth; for 300 nm at 100 μm; for 360 nm at 190 μm; for 400 nm at 250 μm; for 700 nm at 400 μm; for 1.2 μm at 800 μm; for 2 μm at 400 μm; for 2.5 μm at 1μ; and for 400 μm at 30 μm)

Referring to following video, It mentioned that your skin becomes more conductive when you get more nervous, as increasing conductive, skin is easier to lose electrons during noon - blue light exposure.

Does it make sense in physics and biology?

Do you have any suggestions?
Thank you very much for any suggestions (^v^)






Ref :

I see where you're going with this

The galvanic skin response exists because of electrodermal activity (EDA). The traditional theory of EDA holds that skin resistance varies with the state of sweat glands in the skin. Sweating is controlled by the sympathetic nervous system, and skin conductance is an indication of psychological or physiological arousal. In other words, the conductor, sweat, is produced when you're nervous for example. If the sympathetic branch of the autonomic nervous system is highly aroused, then sweat gland activity also increases, which in turn increases skin conductance. In this way, skin conductance can be a measure of emotional and sympathetic responses.
