why white light does not split into its colour component will it pass through the glass slab?

here is your answer OK ☺☺☺☺☺☺
1) Dispersion is the splitting up of white light (or a composite light) into its constituent colours. Dispersion occurs when light is passed through a prism. 2) The dispersion is caused due to the the difference in the angle of deviation for different colours.3) In the case of a glass slab, the opposite sides are parallel and therefore different colors emerge parallel to each other and are seen simultaneously.4) Therefore, dispersion doesn’t occur in a glass slab. In a prism, the dispersion occurring at one face in enhanced by the refraction at the other face, but in a glass slab the dispersion occurring at one face is neutralized by refraction at the other face.5) This is why dispersion does not occour in a glass slab.
