A ray of light is incident on an equilateral triangular glass prism of refractive index 3/2, Calculate the angle through which the ray is minimally deviated in the prism

Answer Details

For the equilateral glass prism A = 600

$\frac{3}{2}\text{Sin}\frac{\left(\frac{Dm+60}{2}\right)}{\left(\frac{60}{2}\right)}=\frac{\left(\text{Sin}\frac{Dm+60}{2}\right)}{0.5}⟹Dm={37.2}^{\circ }$
