A rectangular body has maximum wavelength `lambda_(m)` at `2000 K`. Its corresponding wavelength at `3000 K` will be

A

`3/2 lambda_(m)`

B

`2/3 lambda_(m)`

C

`16/81 lambda_(m)`

D

`81/16 lambda_(m)`

Text Solution

Verified by Experts

The correct Answer is:
B
According to Wien's law, `lambda_(m) prop 1/T`
When temperature becomes `3/2` times `lambda_(m)` becomes `2/3` times.
