lateral displacement is the mechanism in which light changes its path when it travells from one medium to the another.
if the second medium is thicker/denser from the first one then the light moves towards the normal and if the second medium is lighter/rarer than the first medium then the light ray move away from normal.

it is quite difficult to learn the last phenomena. so remember it like this.
if you throw a ball slantly in water then it moves towards normal and if the ball will be thrown slantly out of the water then it will move away from the normal.
always remember that this law of lateral displacement occurs due to speed of light in different mediums.
means speed is the important factor in it.
hope it helps!

lateral displacement also known as lateral shift is the change or deviation of light from its original path when passing tfrom a rarer to a denser medium (moves towards the normal)the distance between the deviated ray and the original ray is called lateral displacement or lateral shift.

Refraction occurs when the speed changes when the lights travels from one medium to another medium. If the light travels from a medium to a denser medium, the light slows down and consequently is refracted towards the normal.thus the distance by which the light has been displaced after its binding thru a glass slab is known as lateral displacement.
Lateral displacement depends upon-
- thickness of glass slab
- angle of incidence
- refractive index of glass slab
- Lateral displacement is directly proportional to the above three factors.
- It is inversely proportional to the wavelength of incident light.

Rajdeep here....
Whenever a light ray refracts in a glass slab, the emergent ray emerges out from the glass slab parallel to the incident ray. There is a distance between the actual emergent ray and the enlarged incident ray. This distance is knows aslateral displacement.
Thus, lateral displacement is the perpendicular distance between the actual emergent ray and the extended incident ray when a light ray suffers refraction from a glass slab.
Thanks!!

Following are the factors on which lateral displacement depends:
The thickness of the glass slab
Refractive index of the glass slab
The angle at which incident ray enters the glass slab.
