On observing light from three different ...

On observing light from three different stars `P`, `Q` and `R`, it was found that intensity of violet colour is maximum in the spectrum of `P`, the intensity of green colour is maximum in the spectrum of `R` and the intensity of red colour is maximum in the spectrum of `Q`. if `T_(P)`, `T_(Q)` and `T_(R)` are respective absolute temperature of `P`, `Q` and `R`. then it can be concluded from the above observation that

A

`T_(P) gt T_(R) gt T_(Q)`

B

`T_(P) lt T_(R) lt T_(Q)`

C

`T_(P) lt T_(Q) lt T_(R)`

D

`T_(P) gt T_(Q) gt T_(R)`

Text Solution

Verified by Experts

`lambda_(V) T_(P) = lambda_(G) T_(R) = lambda_(R) T_(Q) = b` (Wien's law)
`lambda_(R) gt lambda_(G) gt lambda_(V)`
`T_(P) gt T_(R) gt T_(Q)`
