Visible light, AKA white light, travels in straight lines at a very fast speed through the air. Though you can't always see them, it is made up of different colors. When it [light]passes through a prism it slows down as it [the prism] is a denser material and as the light is passed at an angle some Photons enter the prism first and slow down, this pulls the rest of the Photons which have not entered the prism yet causing it to refract. (Some people say the light bends, but this is incorrect as light always travels in a straight line and when it refract it just turns). The colors then separate and can be seen; this is called dispersion.
Triangular prisms are used to disperse light, that is, to break light up into its spectral components (the colors of the rainbow).
Crown glasses like BK7 have a small dispersion, while flint glasses have a much stronger dispersion (for visible light) and thus are more suitable for use in dispersive prisms. Fused quartz is used in the ultraviolet as normal glasses lose their transparency there.
The top angle of the prism can be chosen to guide the dispersion. However, it is typically chosen so that both the incoming and outgoing light rays hit the surface around the Brewster's angle, so that reflection losses are minimized.
Brewster's angle (also known as the polarization angle) is an angle of incidence at which light with a particular division is perfectly transmitted through a transparent surface, with no reflection.

The separation of white light into different colors by a prism is called dispersion.
White light split into colored light is called dispersion. This occurs when white light is passed through a prism, which separates the different colors based on their wavelengths.
This describes the process of dispersion where white light is separated into its component colors by a prism, and then combining these colors through another prism reverts it back to white light. This is due to the dispersion of light wavelengths by the prisms, which are then recombined to form white light.
When white light is separated, it is dispersed into its different constituent colors (spectrum) because each color of light has a different wavelength. This separation is known as dispersion, and it can be observed when white light passes through a prism, creating a rainbow-like spectrum of colors.
White light can be separated into its component colors using a prism or diffraction grating. When white light passes through these materials, it is refracted or diffracted, causing the different colors to bend at different angles due to their varying wavelengths. This separation of colors, known as dispersion, results in the formation of a rainbow spectrum.

Dispersion of white light... ! :D
White is not a colour. It is sensed only by human eye. Actually white is a composite of many colours. Such a composite white light could be spilit up by using a triangular prism. This splitting of composite white light into its constituent colours is called dispersion.
Dispersion
dispersion of white light into its constituent colours
The splitting up of white light into its constituent colors is called dispersion. This occurs when light passes through a medium where its speed changes, causing different colors to refract by different amounts.
