Question

Find the angle of minimum deviation for an equilateral prism made of a material of refractive index 1.732. What is the angle of incidence for this deviation

Answer 1

$\frac{\pi}{ \sqrt{3} }$
is the angle of minimum deviation for an equilateral prism .
$(1 + \sqrt{3} ) \times \frac{\pi}{6}$
is the incident angle for this above deviation .
