If wavelength of maximum intensity of radiations emitted by sun and moon are `0.5xx10^(-6)m` and `10^(-4)`m respectively, the ratio of their temperature is :

A

`1//200`

B

`1//100`

C

`100`

D

`200`.

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda_(1)T_(1)=lamda_(2)T_(2)`
`(T_(1))/(T_(2))=(lamda_(2))/(lamda_(1))=(10^(-4))/(0*5xx10^(-6))=200`.
Thus correct choice is (d).
