For any prism, show that refractive index ‘$n$’ of its material is given by:
$n = \frac{\sin\left(\frac{A + \delta_m}{2}\right)}{\sin\left(\frac{A}{2}\right)}$
where the terms have their usual meaning.
Given: A prism with angle of prism $A$ and angle of minimum deviation $\delta_m$
To show: $n = \frac{\sin\left(\frac{A + \delta_m}{2}\right)}{\sin\left(\frac{A}{2}\right)}$
