A light ray passes through a prism of angle $ heta$ and is re\fracted at an angle $\phi$ to the normal. If the prism is placed in a medium of re\fractive index $n_1$, find the angle of deviation $\delta$ in terms of $ heta$, $\phi$, and $n_1$.

Question

A light ray passes through a prism of angle $	heta$ and is re\fracted at an angle $\phi$ to the normal. If the prism is placed in a medium of re\fractive index $n_1$, find the angle of deviation $\delta$ in terms of $	heta$, $\phi$, and $n_1$.

Accepted Answer

\theta - \phi + \sin^{-1} \left$ \frac{n_1 \sin \phi}{n_2} \right $
