Vedclass · Answer

(B) According to Cauchy's dispersion formula,the refractive index $\mu$ of a material is inversely proportional to the square of the wavelength $\lambda$ of light,expressed as $\mu \approx A + \frac{B}{\lambda^2}$.Since the wavelength of violet light $(\lambda_v)$ is the shortest among the visible spectrum and the wavelength of red light $(\lambda_r)$ is the longest $(\lambda_v Therefore,the refractive index is greatest for the light with the shortest wavelength,which is violet light.
