A light ray passes through a prism of re\fractive index $\mu$ and is deviated by an angle $\delta$. If the angle of incidence is $\alpha$ and the angle of emergence is $\beta$, find the angle of deviation $\delta$ in terms of $\mu$, $\alpha$, and $\beta$.

Question

Accepted Answer

$\delta = \alpha - \beta + \sin^{-1}\left\( \frac{\mu \sin \alpha}{\mu \sin \beta}\right)\ $
