Two stars ' $\mathrm{P}$ ' and ' $\mathrm{Q}$ ' emit yellow and blue light respectively. The relation between their temperatures $\left(\mathrm{T}_{\mathrm{P}}\right.$ and $\left.\mathrm{T}_{\mathrm{Q}}\right)$ is
According to wien's law, $\lambda T=$ constant
$\therefore \mathrm{T} \propto \frac{1}{\lambda}$
wavelength of blue light is less that than of yellow light.
Hence, temperature of $\mathrm{Q}$ is greater than temperature of $\mathrm{P}$.
