Radiation

Question

If there are two bodies at different temperatures, the wavelength of radiation (in which maximum radiation energy is distributed):

Easy

A

will be greater for the body at higher temperature
B

will be greater for the body at lower temperature
C

has no relation with temperature, so will be same for both the bodies
D

none of the above

Solution

According to wein's displacement law $λ T = C O N S T A N T$
$λ α \frac{1}{T}$
BUT E $α T^{4}$
AT EVERY TEMPERATURE AT ALL THE WAVE LENGTHS HEAT ENERGY WILL BE EMITTED.
As the temperature increases the wavelength corresponding to maximum energy emitted will be shifted towards shorter wavelength range.
