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

Accepted Answer

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