If wavelengths of maximum intensity of r...

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

`lamda_(m)T=` constant
`therefore (T_(1))/(T_(2))=(lamda_(2))/(lamda_(1))" "therefore (10^(-4))/(0.5xx10^(-5))=200`.
