The refractive index of the material of an equilateral prism is 1.6. The angle of minimum deviation due to the prism would be

Options:

Answer:

Solution:

Here, $μ = 1.6, A = 6 0^{\circ}$ $As, μ = \frac{sin ( \frac{A + δ _{m}}{2} )}{sin ( \frac{A}{2} )} ∴ sin (\frac{6 0 ^{\circ} + δ _{m}}{2}) = 1.6 sin (\frac{6 0 ^{\circ}}{2}) \Rightarrow sin (\frac{6 0 ^{\circ} + δ _{m}}{2}) = 0.8 \Rightarrow δ_{m} = 46. 3^{\circ}$
