Question

State (i) Stefan-Boltmann law and (ii) Wein’s displacement law.

Answer 1

Answer:

Stefan Boltzmann law states that the total energy radiated per unit surface area of black body across all wavelength per unit time.

Whereas Wien's displacement states that the spectral radiance of black body radiation per unit wavelength.

Answer 2

Answer:

Stefan Boltzmann law describes the power radiated from a black body in terms of its temperature whereas Wien's displacement shows curve (for black body) for different temperatures peaks at a wavelength inversely proportional to temperature.

Stefan Boltzmann law states that the total energy radiated per unit surface area of black body across all wavelength per unit time. Whereas Wien's displacement states that the spectral radiance of black body radiation per unit wavelength.
