Answer to Question 1

Answer: White clothing reflects all colors of light and absorbs very little of the light. It also reflects infrared radiation. Since the energy of the infrared and light radiation is reflected away, we are not warmed by it. Black clothing absorbs almost all of the radiation that falls on it, infrared as well as light. The energy absorbed by black clothing is felt as heat and warms us. So in general, white clothing is a better reflector and black clothing is a better absorber.
