1. 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 temperatures of \(P\), \(Q\) and \(R\), then it can be concluded from the above observations that
