The Stefan-Boltzmann law provides the relation temperature of a black body with the power radiated by it. Specifically, the Stefan-Boltzmann law gives us the total energy radiated of a black body per unit surface area for different wavelengths per unit time (also known as the black-body radiant emittance). According to Stefan's law, the amount of energy emitted by a black body is proportional to the 4th power of temperature. E=
P
A
=eσT4 Where, E= Energy emitted, P =power σ= Stefan's constant and σ=5.670373×10−8Wm−2K−4 T= Absolute temperature, A= Area of the surface ⇒E∝T4 Since radiations are emitted in the form of energy waves hence option (C) is the correct option and all other options are incorrect.
