When light traverse the interface between two transparent material with a different refraction index it undergo refraction, that is the angle of incidence on the interface is different from the angle with which the light comes out from the surface itself. In a prism refraction happens as the light passes from air to the prism material (generally glass or a polymer like PMMA, also called Plexiglas) and when the light leaves the prism, passing from it to air again. Since the difference of incident and emerging angles is opposite passing from air to prism and from prism to air (let us call that angle q) the total diffraction angle due to the passage through a prism is 2 q. Since q depends on the light wavelength (that is on the light color) different colors are diffracted at different angles and the light at the prism output appears as decomposed in different rays, exiting from the prism with different angles, one for each color. Doping the prism glass with impurities increasing a lot its refraction index, complete refraction can be obtained for selected light colors. These colors at the first interface with the prism have a refraction angle greater than 90° and light of those colors does not enter into the prism. Thus colors suffering total refractions lack from the prism output light.
Violet light changes direction the most when it leaves a triangular prism because it has the shortest wavelength and highest frequency compared to other colors in the visible spectrum. This causes it to refract more as it passes through the different mediums inside the prism.
A prism works by refracting white light into its component colors, which have different wavelengths. This separation of colors occurs due to the different angles at which each color of light is bent as it passes through the prism, known as dispersion. This results in the colorful spectrum that is seen when looking at white light through a prism.
When a light ray enters a prism, it is refracted, causing the light ray to change direction due to the different speeds of light in the different materials of the prism. The light ray is then further refracted as it exits the prism, resulting in the separation of the light into its component colors, creating a rainbow effect known as dispersion.
A prism separates white light into its spectral colors. When green light enters a prism, it will refract and split into a spectrum of colors, including green, as well as other colors like blue and yellow.

Light bends in glass dependent on its thickness. Blue comes from the thin part and red from the thick part of a prism.

Violet light does not split into different colors when it passes through a prism.If it goes in violet, it comes out violet.White light is a combination of light of many colors. If you pass white light througha prism, a spread of different colors will come out of the prism, because each colorbends through a slightly different angle on its way through the prism.
