Both Sun and a Star have Helium and Hydrogen but the sun light is yellow or orange and the star light is white.
Why?
why only we can see scattering of light only in turbid water.
If light is part of a spectrum why can we only see light and not the other parts of the spectrum? If we can only see light why can we infrared filters in a camera? And will we we ever evolve into creatures that can see other forms of energy too?
