Radiation is the process by which energy can be transferred from one body to another through electromagnetic waves in the absence of an intervening medium. If an intervening medium is present, it must be at least partially transparent in order for the radiant energy transfer to take place. Energy is continuously radiated from all substances that are above absolute zero (0 K) in temperature. If a black body is warmer than its environment, it radiates more energy than it receives and the environment receives more energy than it radiates. There is, thus, a net transfer of energy from the warm black body to the cooler environment. The basic problem is to determine the direction and rate of this net energy transfer.
