Vedclass · Answer

(D) The refractive index of glass is $\mu_g = \frac{3}{2}$ and the refractive index of water is $\mu_w = \frac{4}{3}$.When light travels from a denser medium (glass) to a rarer medium (water),the critical angle $C$ is given by the formula $\sin C = \frac{\mu_w}{\mu_g}$.Substituting the given values:$\sin C = \frac{4/3}{3/2} = \frac{4}{3} 	imes \frac{2}{3} = \frac{8}{9}$.Therefore,the critical angle $C = \sin^{-1}\left(\frac{8}{9}ight)$.

The refractive index of glass is $\frac{3}{2}$ and that of water is $\frac{4}{3}$. The critical angle for a ray of light going from glass to water is
