Thermal Physics: Practice Problem & Solution

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 color is maximum in the spectrum of R and the intensity of red color 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: (2015)
$T_P > T_R > T_Q$
$T_P < T_R < T_Q$
$T_P < T_Q < T_R$
$T_P > T_Q > T_R$

Solution Explained:

To solve this problem, we apply the core principles of Thermal Physics. Understanding the underlying formula is key to arriving at the correct answer below:

The wavelengths corresponding to maximum intensity are $\lambda_P < \lambda_R T_R > T_Q$.
