Question given:
To explain how the white light gets dispered.
Answer:-
Whenever the white light is passed through a glass prism it splits white light in seven constituent colours that is violet, indigo, blue green ,yellow, orange and red(VIBGYOR).
In the air or vacuum medium,all the colors get propagated with same speed. But in the case of material light raised propagates with different speeds.
In the glass prism,speed of violet color is maximum but in red it is minimum.
For this vary reason,red color bends minimum towards the base other than violet that bends maximum.
In this way,the white light split into the seven colours.

Prism:- It is a piece of transparent material that is bounded by two plane surface that is inclined at one angle.
Answer:
The splitting up of white light into seven colours on passing through a transparent medium like a glass prism is called dispersion of light.Cause of dispersion ..
