Question
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 TP, TQ and TR are the respective absolute temperature of P, Q and R, then it can conclude from the above observations that
-
TP > TQ>TR
-
TP > TR> TQ
-
TP > TR < TQ
-
TP < TQ < TR
Solution
B.
TP > TR> TQ
We know from Weins displacement law
