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

Options

A. `T_(P)gtT_(R)gtT_(Q)`
B. `T_(P)ltT_(R)ltT_(Q)`
C. `T_(P)ltT_(Q)ltT_(R)`
D. `T_(P)ltT_(Q)ltT_(R)`

Answer

A

Explanation

From wien's displacemnt law, `lambda_(m)prop (1)/(T)`
Given, `(lambda_(m))_(p) lt (lambda_(m))_(R)lt (lambda_(m))Q`.
so `T_(P)gtT_(R)gtT_(Q)`.
