Light rays travel from vacuum into a glass whose refractive index is $1.5$ . If the angle of incidence is $30°$ , calculate the angle of refraction inside the glass.

The angle of refraction is found by using the Snell's law,

$\frac{\sin i}{\sin r} = \frac{v_{2}}{μ_{1}}$
$\frac{\sin i}{\sin r} = \frac{μ_{2}}{μ_{1}}$

By applying the known values in the formula, we get,

$r$

$=$

$°$
