Question

state wein's displacement law and plot a graph shot erergy emitted verses wavelength for a blackbody different temperature​

Answer 1

Answer:

Wein’s displacement law:

The wavelength (λ

m

) Corresponding to maximum energy emitted by a black body is inversely proportional to its absolute temperature. i.e. λ

m

∝(

T

1

) or λ

m

T=b. where b is a constant, called Wein’s constant. The radiation emitted by a black body is called black body radiation. The distribution of energy of black body radiation at different temperatures is as shown in the figure.

The energy distribution is not uniform. There is a particular wavelength λ

m

at which the energy emitted is maximum. The wavelength λ

m

for which the intensity is maximum decreases with an increase in temperature.
