Emissive power
The radiation process is different for different materials and also the radiation process is will be different for a body at different temperatures. Obviously, we can say that the radiation for a body depends upon the surface area of the body, its temperature, the temperature of the surrounding, and time for which the radiation takes place.
Emissive power of a body at temperature corresponding to a wavelength is defined as the energy radiated by the body per sec per unit area of the body for unit range of wavelength.
