Question 289: Ray Optics

Question

A horizontal ray of light is incident on the right angled prism with prism angle $$6^{\circ}$$. If the refractive index of the material of the prism is 1.5 , then the angle of emergence will be:

Accepted Answer

$$A = {r_1} + {r_2} = 6^\circ $$
$$\mu  = 1.5{{\sin e} \over {\sin {r_2}}} = {{\sin e} \over {\sin 6}}$$
$$\sin e = 1.5 	imes 6^\circ $$
$$e \simeq 9^\circ $$

Answer

$$9^{\circ}$$

Answer

$$10^{\circ}$$

Answer

$$4^{\circ}$$

Answer

$$6^{\circ}$$
