The radiation energy density per unit wavelength at a temperature T has a maximum at a wavelength` lambda_(0)`. At temperature 2T, it will have a maximum wavelength

A

`4lamda_(0)`

B

`2lamda_(0)`

C

`(lamda_(0))/(2)`

D

`(lamda_(0))/(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
Using Wien's displacement law,
`lamda_(1)T_(1)=lamda_(2)T_(2)`
`implieslamda_(0)T=lamda_(2)2T`
`lamda_(2)=(lamda_(0))/(2)`
