Question

why there is lateral displacement in glass slab but not in prism ?​

Answer 1

Heya!

Here is ur answer..

Dispersion :

Splitting of light is called as Dispersion.

Dispersion occurs due to difference in the angle for the diff.colours..

In glass slab..the two surfaces are parallel so the lateral dispersion occurs.

But, In prism the two opp.surfaces are not parallel..so there will be no lateral dispersion.

Hope it helps. u

Answer 2

Spilliting of light and formation of VIBGYOR is known as Dispersion.

Dispersion occurs due to the difference in the angle for the diffused colours

In a glass slab the two surfaces are parallel so the lateral dispersal occurs

But, in prism the two opposite surfaces are not parallel, so there is no lateral dispersion.
