Key Concepts

Dispersion

Dispersion is the phenomenon where the speed of light in a medium depends on its wavelength, causing different colors to refract by different amounts. This effect splits white light into its constituent colors when passing through a prism and is fundamental in explaining why a spectrum appears.

Refraction

Refraction is the bending of light as it passes from one medium to another with different optical densities. It is the underlying process that causes light to change direction and, when combined with dispersion, leads to the separation of white light into various colors.

White Light

White light is composed of a mixture of all visible wavelengths or colors. When it undergoes dispersion, these mixed wavelengths are separated, revealing the individual colors that make up the light.

Prism

A prism is a transparent optical element with flat, polished surfaces that refract light. It is commonly used to demonstrate dispersion because its shape causes white light to split into a spectrum of colors as different wavelengths are bent by different amounts.
