The refraction through the prisms are as shown. Pick out the WRONG statement from the following. Path of the light ray in
1 (a) is correct, if \({n_2} > {n_1}\) and \({n_2} > {n_3}\)
2 (b) is correct if \({n_1} = {n_2}\) and \({n_2} > {n_3}\)
3 (c) is correct if \({n_2} < {n_1}\) and \({n_2} = {n_3}\)
4 (d) is correct if \({n_1} = {n_2}\) and \({n_2} = {n_3}\)
Explanation:
Option (4) is incorrect as the directions of refraction of light rays in (d) do not match the relations between the refractive indices given in (4).

For an angle of incidence \(\theta \) on an equilateral prism of refractive index \(\sqrt 3 \) the ray refracted is parallel to the base inside the prism. The value of \(\theta \) is
1 45°
2 30°
3 75°
4 60°
Explanation:
The given ray is in minimum deviation condition. By applying Snell’s law \(\sin \theta = \sqrt 3 \sin 30^\circ = \frac{{\sqrt 3 }}{2}\) \(\theta = 60^\circ \)
