It splits the light into the various visible wavelengths that are known as the spectrum of light.

A prism refracts light rays, causing them to bend and separate into different colors. This effect is called dispersion, where each color of light is refracted by a slightly different angle due to its wavelength, resulting in a rainbow-like spectrum.
When light rays pass through a prism, they refract or bend due to the change in speed as they move from one medium to another. This bending is caused by the difference in the refractive index of the prism material compared to the surrounding medium. The direction of bending is determined by the angle at which the light enters and emerges from the prism, according to Snell's Law. The thickness of the prism itself does not play a significant role in the bending of light rays within the prism.
A prism bends light rays. White light is made up of many different wave lengths of light. A prism bends each wave length a different amount, that is why different colors are produced from the output side of a prism.
When light passes through an inverted prism, the light rays are refracted in the opposite direction compared to when passing through a regular prism. This causes the light to diverge rather than converge, resulting in a wider dispersal of the light spectrum.
To separate the rays in a light beam and make a rainbow, you can use a prism or water droplets in the atmosphere. When light enters a prism, it is refracted at different angles depending on its wavelength, causing the different colors in the light spectrum to separate. Similarly, when sunlight passes through water droplets in the air, it is refracted and dispersed, creating a rainbow.
The splitting of light rays into different colors is called dispersion. This occurs when light rays pass through a prism or other refractive medium, causing the different wavelengths of light to refract at different angles and separate into the colors of the rainbow.
