Wien's constant is `2892xx10^-6 mKs` and value of `lamda_(m)` from moon is `14.46` micron. What is the surface temperature ?

A

100 K

B

200 K

C

400 K

D

600 K.

Text Solution

Verified by Experts

The correct Answer is:
B
`lamda_(m)*T=b`.
`T=(*2892xx10^(-2))/(14*46xx10^(-6))=200K`
Thus correct choice is (b).
