For a prism kept in air it is found that for an angle of incidence $6 0^{\circ}$ , the angle of refraction ' $A$ ', angle of deviation ' $δ$ ' and angle of emergence ' $e$ ' become equal. Then the refractive index of the prism is

Answer:

Solution:

$δ = i + e - A$ ; for $i = 6 0^{\circ}$ given $A = δ = e$

So $A = δ = e = 6 0^{\circ}$

Snell's law at first face: $1 \times sin 6 0^{\circ} = μ sin 3 0^{\circ}$

$μ = 3 = 1.73$
