3.White objects absorb no colored light and reflect all; black objects absorb all light and reflect none. Why should we wear dark clothes in the winter and light-colored clothes in the summer?
The color of an object depends on the reflection and the absorbtion of light. How? Actually, the color of an object depends on three things, the light source, the object properties, and the human observer. All three are necessary for an object to have color. As far as the object itself, it is the property of absorbing different amounts of the various wavelengths of light that impart color to the object. Whatever light is not absorbed is either reflected or transmitted and that is what we see. Darker colors absorb it, and light reflects it. Hence, darker colors are hotter because they hold in the heat.
Light is heat. So if you absorb light, you absorb heat. Conversely, if you reflect light, you reflect heat. So...
