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 $T_{P}, T_{Q}\ and\ T_{R}$ are the respective absolute temperature of P, Q and R, then it can be concluded from the above observations that(a) $T_{P}\ \textgreater \ T_{R}\ \textgreater \ T_{Q}$(b) $T_{P}\ \textless \ T_{R}\ \textless \ T_{Q}$(c) $T_{P}\ \textless \ T_{Q}\ \textless \ T_{R}$(d) $T_{P}\ \textgreater \ T_{Q}\ \textgreater \ T_{R}$

Answer 1

Correct option (d) Tp > TR TQ

Explanation:

According to Wein's displacement law

λm T = constant

For star P, intensity of violet colour is maximum For star Q, intensity of red colour is maximum. For star R, intensity of green colour is maximum.
