It's All Based On The Law Of Physics,
[ Def : the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms ]
How light interacts with objects determines what we see. Light rays that come from a source such as the sun reflect off items and enter our eye. Chandrasekhar explains: "When the energy is taken up by the object, it's called absorption, and when" the energy "is bounced back by" the object, "it's called reflection." Objects are selective about which colors they will absorb or reflect. "A black object is black because it's absorbing all the light; it's not reflecting any color,"
Chandrasekhar says. White objects reflect all color.
Why do you feel hot when you wear black clothes? While black objects absorb the energy from all colors and become hot, the objects gradually release some of that energy back into the air
around it. Your body receives part of the heat energy that the black clothing radiates. To better understand light waves, Chandrasekhar suggests wearing diffraction grating glasses. Examine different light sources, such as LED versus fluorescent bulbs, and compare what you see. Be sure to never look directly into the sun, even with your glasses, as the light can damage your eyes.
