If wavelength of maximum intensity of radiation emitted by Sun and Moon are `0.5 xx 10^(-6)`m and `10^(-4)` m respectively, then the ratio of their temperature is

A

`1: 100`

B

`1: 200`

C

`200:1`

D

`400:1`

Text Solution

Verified by Experts

The correct Answer is:
C
According to Wien.s displacement law,
`lamda_(m)T=` constant
`:. (T_(1))/(T_(2)) = (lamda_(m_(2)))/(lamda_(m_(1))) = (10^(-4))/(0.5 xx 10^(-6)) = 200`
