Black body at a temperature of `1640K` has the wavelength corresponding to maximum emission equal to `1.75mu m` Assuming the moon to be a perfectly black body the temperature of the moon if the wavelength corresponding to maximum emission is `14.35mum` is .

A

100 K

B

150 K

C

200 K

D

250 K

Text Solution

Verified by Experts

The correct Answer is:
C

`(T_(2))/(T_(1))=(lamda_(m_(1)))/(lamda_(m_(2)))=(1.75)/(14.35)`
`T_(2)=(1.75)/(14.35)xx1640=200K`
