Answer To Question 211

A211: A black body is an idealized body that is a perfect radiator and perfect absorber of electromagnetic radiation. A black body not only absorbs all wavelengths of energy and radiates at all wavelengths, but it does this at the maximum possible intensity for any given temperature. It doesn't necessarily look black. A star is a good approximation to a black body since stellar gases are very good absorbers of energy.
