The plots of intensity versus wavelength...

The plots of intensity versus wavelength for three black bodies at temperature `T_1,T_2 and T_3` respectively are as shown. Their temperatures are such that

A

`T_(1) gt T_(2) gt T_(3)`

B

`T_(1) gt T_(3) gt T_(2)`

C

`T_(2) gt T_(3) gt T_(1)`

D

`T_(3) gt T_(2) gt T_(1)`

Text Solution

Verified by Experts

The correct Answer is:
B
According to Wein's law `lambda_(m) prop 1/T` and from the figure `(lambda_m)_(1) lt (lambda_m)_(3) lt (lambda_m)_(2)` therefore `T_(1) gt T_(3) gt T_(2)`.
