Good reflectors are typically poor absorbers. An example of this would be the use of a metal. It would be efficient at reflecting heat but not at absorbing it. If a surface is rough, it will absorb more of the heat emitted. Color also affects the degree of absorption: darker, greater where the light is less. This then has an impact on the principle that good absorbers are usually good radiators, and the same goes for poor people. What is the best absorber? It is any surface that absorbs all radiant energy such as black
