For a black body, the monochromatic emittance (Eπ ) of the black body and the wavelength (λ ) of the radiation emitted.
So, at a given temperature of black body :→ a) The energy emitted is not distributed uniformly amongst all wavelengths. b) The energy emitted in maximum corresponding to a certain wavelength (λm) and its falls on either side of it. As temperature of black body is increased.
a) The total energy emitted rapidly increases for any given wavelength.
b) The wavelength corresponding to which energy emitted is maximum is shifted towards shorter wavelength side i. e, λ m decreases with rise in temperature
