A ray of light in air is incident at an angle of $60.0^{\circ}$ with the surface of some benzene con-
tained in a shallow tank made of crown glass.
What is the angle of refraction of the light ray when it enters the glass at the bottom of the tank?

Key Concepts

Refraction

Refraction is the bending of a light ray as it passes from one medium into another with a different optical density. This change in direction occurs because light travels at different speeds in different media, and the amount of bending depends on how significantly the speed changes at the interface.

Snell's Law

Snell's Law is the principle that quantitatively relates the angles of incidence and refraction to the indices of refraction of the two media involved. It is expressed by the equation n? sin(??) = n? sin(??), where n? and n? are the refractive indices of the first and second medium, and ?? and ?? are the angles of incidence and refraction measured from the normal.

Index of Refraction

The index of refraction is a dimensionless number representing how much the speed of light is reduced inside a medium compared to its speed in a vacuum. It is a fundamental property of the material and plays a critical role in determining the degree to which light bends when entering or exiting the medium.
