The index of refraction for red light in a certain liquid is 1.305 the index of refraction for violet light in the same liquid is 1.336 . Find the dispersion $\left(\theta_{v}-\theta_{r}\right)$ for red and violet light when both are incident from air onto the flat surface of the liquid at an angle of $45.00^{\circ}$ to the normal.

Key Concepts

Index of Refraction

Index of refraction is a measure of how much the speed of light is reduced inside a medium compared to vacuum. It is a fundamental property of materials that determines how light propagates through them, influencing both the speed and bending of light rays when entering the material.

Snell’s Law

Snell’s Law is the principle that describes how light bends, or refracts, when it passes from one medium into another with a different index of refraction. It mathematically relates the angles of incidence and refraction to the indices of refraction of the two media.

Dispersion

Dispersion refers to the phenomenon where light separates into its component colors because different wavelengths (colors) of light are refracted by different amounts. This is due to the wavelength dependency of the index of refraction, resulting in different bending angles for different colors as they pass through a medium.
