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

`4/9 lambda_(m)`

D

`9/4 lambda_(m)`

Text Solution

Verified by Experts

The correct Answer is:
B
`lambda_(m2) = (T_1)/(T_2) xx lambda_(m1)=2000/3000xxlambda_(m1) = 2/3 lambda_(m1) = 2/3 lambda_(m)`.
