The plots of intensity versus wavelength...

The plots of intensity versus wavelength for three black bodies at temperatures `T_(1),T_(2)` and `T_(3)` respectively are shown in Their temperatures are shown in How their temperatures are related ?
.

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
`lambda_(1) T_(1) = lambda_(2)T_(2) = lambda_(3)T_(3) = "b so" T_(1) gt T_(3) gt T_(2)`
