Question

Refractive index of a prism with angle of prism $60^o$ is $\sqrt{2}$, the angle of incidence at minimum deviation is\

Professor PC Thomas Classes · Answer

$\quad \mathrm{d}=\mathrm{i}_{1}+\mathrm{i}_{2}-\mathrm{A}$ When $\mathrm{d}=\mathrm{D}$, the angle of minimum deviation $\mathrm{i}_{1}=\mathrm{i}_{2}=\mathrm{i}$\ $\mathrm{D}=2 \mathrm{i}-\mathrm{A} =\frac{\mathrm{A}+\mathrm{D}}{2}=$\
