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.
What else can I help you with?
Why is white light dispersed?
White light is dispersed because it is composed of different colors with varying wavelengths. When white light passes through a prism or a diffraction grating, each color is refracted at a slightly different angle, causing the different colors to spread out and form a spectrum. This dispersion occurs due to the differences in the speed of light in the medium for each color.
What would you use to split white light into colors?
If white light is shined through a prism, it will be dispersed into colors.
What All of the visable color light waves together make up?
All visible color light waves together make up white light. White light is a combination of all the colors in the visible spectrum, which can be seen when light is dispersed through a prism.
What appearance does emulsions have when light shines out?
Emulsions typically appear white or opaque when light shines through them. This is due to the scattering of light by the dispersed particles in the emulsion, which causes the light to be reflected in multiple directions.
All of the colors in white light are visable when white light is?
Yes, although the separate colors are perceived to your eye as white. If you have a prism you can separate white light into the continuous color spectrum. This effect is also achieved in rainbows.

How white light will appear once passed through a soap bubble?
It will have been dispersed into the spectrum
What spectrum does white light form?
when dispersed through a prism: Visible spectrum of light (rainbow) part of (very small fraction) electromagnets spectrum

How is lupin dispersed?
lupins are dispersed by watering them and giving them light

All visible color light waves together make up white light. White light is a combination of all the colors in the visible spectrum, which can be seen when light is dispersed through a prism.
Why white light is not dispersed in air?
Because all the constituent colors of white light have same speed so, refractive index for the constituent colors are same for air as a result dispersion doesn't occur.
All of the colors in white light are visable when white light is?
Yes, although the separate colors are perceived to your eye as white. If you have a prism you can separate white light into the continuous color spectrum. This effect is also achieved in rainbows.
Why light is dispersed by a prism?
Light is dispersed by a prism because it consists of different colors with different wavelengths. When light enters a prism, it changes speed and is refracted at different angles based on its wavelength, causing the colors to spread out. This dispersion is responsible for the rainbow of colors seen when white light passes through a prism.
What is created when white light us passed through a prism?
When white light is passed through a prism, it is dispersed into its component colors, forming a spectrum. This spectrum consists of colors of different wavelengths ranging from red to violet.
What cause the disperse in white light?
White light is made up of 7 colours. When put through a prism like a raindrop or a glass block, the 7 colours all travel at different speeds, because some slow down more than others. Thus, light is dispersed into it's spectrum
