A ray of light passes from air into a glass slab of re\fractive index $\mu$ at an angle of incidence $ heta_i$. If the angle of re\fraction is $ heta_r$, what is the relationship between $ heta_i$ and $ heta_r$?

Question

A ray of light passes from air into a glass slab of re\fractive index $\mu$ at an angle of incidence $	heta_i$. If the angle of re\fraction is $	heta_r$, what is the relationship between $	heta_i$ and $	heta_r$?

Accepted Answer

\sin 	heta_i = \frac{\sin 	heta_r}{\mu}
