Please can anyone explain for why our fingers turn bright red / orange , when we keep our finger on the flashlight of phone ?
Answers
Answer:
one color of light passes completely through your hand- and that's why it looks red. All of the other colors are completely absorbed, either by the skin, bones, muscles, blood or other cells in your body.
This happens because the light is passing through your red blood cells, which absorb most of the non-red colors in the white light emitted by the flashlight. ... Light gets absorbed in your skin then it gets bounced around before getting re-emitted.
Answer:
Given below is the answer
Explanation:
The human body is transparent to near-infrared and red light (in the range of 600-1000 nm wavelength). With the exception of red, all visible light wavelengths are absorbed. The hue of the blood has nothing to do with this. Your hand would be the same colour if you turned on a flashlight after passing away and instructed the mortician to replace all of your blood with embalming fluid. Skin is actually extremely transparent, but when light shines on it, it looks to be flesh-toned (this is why people have a blue tint when their blood doesn't oxidise, for example). Your fingers are full of (for the sensitive individuals) when you shine a flashlight through your skin, you can see through the transparent skin into what's inside.
