Question
On observing light from three different stars P, Q and R, it was found that intensity of violet color is maximum in the spectrum of P, the intensity of green colour is maximum in the spectrum of R and the intensity or red colour is maximum in the spectrum of Q. If TP, TQ and TR are the respective absolute temperatures of P, Q and R, then it can be concluded from the above observation that :
Options
A.TP > TR > TQ
B.TP < TR < TQ
C.TP < TQ < TR
D.TP > TQ > TR
Solution
From Weins Displacement law
λ ∝ 1/T
So from Sequence VIBGYOR
RED has maximum wavelength so Tempreature will be minimum similarly we can make sequence.
Thus Option A is correct
