Find the value of the angle of emergence from the prism. Refractive index of the glass is $\sqrt{3}$.

Q. A glass prism of refractive index $1.5$ is placed in water of refractive index $1.33$. The minimum value of the angle of the prism so that it will not be possible to have any emergent ray is :

Q. Trace the path of a ray of light passing through a glass prism $ABC$ as shown in the figure. If the refractive index of glass is $\sqrt{3}$, then find out the value of the angle of emergence from the prism.

Q. Light falls at normal incidence on one face of a glass prism of refractive index $\sqrt{2}$. Then the angle of emergence when the angle of the prism is 45${}^{\circ }$

Q. A thin prism $P_1$ with angle $4^o$ and made from glass of refractive index $1.54$ is combined with another prism $P_2$ made from glass of refractive index $1.72$ to produce dispersion without deviation. What is the angle of the prism $P_2$?
