Define emissive power and coefficient of emission of a body
Dear Student ,
Emissive power is defined as the amount of radiant thermal energy emitted from a unit surface area of hot body per unit time.
Einstein coefficients are mathematical quantities which are a measure of the probability of absorption or emission of light by an atom or molecule .
