WIEN'S DISPLACEMENT LAW

A

`lambdaT`=constant

B

`lamdba//T`=constant

C

`lambda prop (1//T)`

D

both (b) and (c)

Text Solution

Verified by Experts

The correct Answer is:
D
Wien's displacement law states that the absolute temperature of a black body and the peak wavelength of its radiations are inversely proportional. i.e., ` lambda prop 1//T or lambda T`=constant
