Polar bear strands are not white #Shorts #Short

The hair of a polar bear looks white because the air spaces in each hair scatter light of all colors. The color white becomes visible to our eyes when an object reflects back all of the visible wavelengths of light, rather than absorbing some of the wavelengths.
At one time it was suggested that the polar bear hairs might have some of the properties of optical fibers. Apparently this is not the case.
