Dark side Of the moon Effect

When light enters a different medium (such as glass, clear plastic, water) it bends. This is refraction. You can see this if you stick a straight stick into water; it looks like it bends when it enters the water. That is refraction.
White light is made up of all the colors of the rainbow. Each color bends a different amount. This is why, when white light passes through a prism, a rainbow of colored light comes out the other side.
Each color of light has a different wavelength.

White light is the combination of lots of different colours of light. And the each colour of light (ranging from infra red, through the visible spectrum, to ultra-violet light) is dictated by its wavelength. When white light hits a prism, it separates the white light into its different constituents of wave length, creating a rainbow effect. That's the refraction of light through prisms.

i think u meant dispersion
refraction is the phenomenon observed when light travels from one medium (say refractive index n1) to some other medium(n2)
when white light is incident on to a prism the phenomenon of seeing different colours is called dispersion
at the heart of dispersion is refraction but there is a difference
white light consists of all the seven colours
when this falls on a prism each colour(wavelength) 'sees' a different refractive index and hence deviates at a different angle hence we see different colours

splitting of white light in 7 colors when it passes thru prism is called refraction of light through prisms.
it takes place bcoz different colors have different frequency

Refraction of light is the splitting up of white light into its components when it passes throug a prism.
White light is actually made up of 7 other light colours and when it passes thru a prism, it is separated into its components.

Light bends when it changes speed. A prism forces light to slow down, so the light bends at its surface. Some colors are forces to slow down more than others, so they bend more. So mixed-frequency light (like white light) can be broken into the monochromatic components of its spectrum (pretty rainbow).

prism is a substance made of medium other than air in which incident and emergent rays are not parallel
