Prism is the best example to learn about dispersion of light.
What dispersion is?
It is the spliting of white light into its constitueny colours.
It happens because every constituent light in white light is having a different wave length.
When white light is passed through a glass prism it splits the white light into its constituent colour according to their wave length.
Its series can be remembered by the acronym of VIBGYOR that is voilet, indigo, green, yellow, orange and red.
Less deviated light is red which is having higher wave length wheare as most deviated light is indigo which is having least wave length.
They are arranged in the descending order of wave length from top to bottom in plane of glass prism.
