​A glass has refractive index μ with respect to air and the critical angle for a ray of light going from glass to air is θ. If a ray of light is incident from air on the glass with angle of incidence θ, the corresponding angle of refraction is ?

Dear Student,

Please find below the solution to the asked query:

$$\begin{gathered} According o snell\text{'}s law, \\ 1\times \sin i=\mu \times \sin r\Rightarrow r={\sin }^{-1}\left(\frac{\sin i}{\mu }\right) \end{gathered}$$
