If wavelengths of maximum intensity of radiations emitted by the sun and the moon are `0.5xx 10^(-6)m` and `10^(-4)m` respectively, the ratio of their temperatures is

A

`1//100`

B

`1//200`

C

100

D

200

Text Solution

Verified by Experts

The correct Answer is:
D
Since, `lambda_mT` = constant
`implies(T_1)/(T_2)=(lambda_2)/(lambda_1) implies (10^(-4))/(0.5 xx 10^(-5))=200`
