Light in vacuum is incident on the surface of a glass slab. In the vaccum the beam makes an angle of `32.0^(@)` with the normal to the surface while in the glass it makes an angle of `16.0^(@)` with the normal . What is the index of refraction of the glass ?

Explanation

To find the index of refraction of the glass slab when light travels from vacuum into glass, we can use Snell's Law, which states:

\[ \frac{\sin i}{\sin r} = n \]

where:
- \( i \) is the angle of incidence (the angle in vacuum),
