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  ${\mathrm{T}}_{\mathrm{P}},{\mathrm{T}}_{\mathrm{Q}}\text{ and }{\mathrm{T}}_{\mathrm{R}}$ are the respective absolute temperatures of P, Q and R, then it can be concluded from the above observations that
