The blue star has a higher temperature.

Vedclass · Answer

(D) According to Wien's Displacement Law, the wavelength of maximum emission $(\lambda_m)$ is inversely proportional to the absolute temperature $(T)$ of the black body, given by $\lambda_m T = b$, where $b$ is Wien's constant.Since the wavelength of red light is greater than the wavelength of blue light $(\lambda_{red} > \lambda_{blue})$, it follows that the temperature of the red star must be lower than the temperature of the blue star $(T_{red} Therefore, the blue star has a higher temperature.
