What will be the ratio of temperatures of sun and moon if the wavelengths of their maximum emission radiations rates are `140A^(@)` and `4200A^(@)` respectively .

A

`1:30`

B

`30:1`

C

`42:14`

D

`14:42`

Text Solution

Verified by Experts

The correct Answer is:
B
`(T_(1))/(T_(2))=(lamda_(m_(2)))/(lamda_(m_(1)))=(4200)/(140)=(30)/(1)`
