This spreading out of the beam of light is called dispersion or chromatic dispersion. This can be seen when sunlight passes through a glass prism. Dispersion can cause problems with camera lenses and must be minimized.

This Demonstration shows the dispersion of white light through a prism as the incidence angle is varied. ... Thus, when the ray of white light passes through a prism, the colors refract at different angles.

As visible light penetrates a glass prism from the right, it is refracted, and separated into an array of visible colors. ... This separtion of white light into its individual colors is known as dispersion of light.

3 Dispersion of the light passing through a prism ... This phenomenon is known as "dispersion of the light through a prism" and it's also responsible for rainbows during storms: as a matter of fact, each raindrop can be regarded as a little prism;

Dispersion of Light using a Prism ... The incident white light is broken into its component colours as it passes through the prism. The red light is refracted less than the violet light so that when they emerge from the prism they are travelling in different directions.
