Vedclass · Answer

(C) According to Wien's displacement law, the wavelength corresponding to maximum intensity $(\lambda_m)$ is inversely proportional to the absolute temperature $(T)$ of the black body, i.e., $\lambda_m T = 	ext{constant}$.Since the wavelength of red light $(\lambda_r)$ is the largest, yellow light $(\lambda_y)$ is intermediate, and blue light $(\lambda_b)$ is the smallest $(\lambda_r > \lambda_y > \lambda_b)$, the corresponding temperatures will follow the inverse order.Therefore, $T_r Given that star $A$ emits maximum intensity in red, $B$ in blue, and $C$ in yellow, we have $T_A Thus, the temperature of $B$ is maximum, $A$ is minimum, and $C$ is intermediate.

On investigation of light from three different stars $A, B$ and $C$, it was found that in the spectrum of $A$ the intensity of red colour is maximum, in $B$ the intensity of blue colour is maximum and in $C$ the intensity of yellow colour is maximum. From these observations, it can be concluded that
