What is the relation between incident ray and emergent ray?
The incident ray is the ray of light that first strikes the surface of a medium or interface, while the emergent ray is the ray of light that exits the medium after being refracted or reflected. The direction of the emergent ray depends on the angle of incidence and the properties of the medium.
Is incident ray parallel to the emergent ray through two glass slab of different refractive index?
No, the incident ray and emergent ray will not be parallel if the glass slabs have different refractive indices. This is because the light rays will experience refraction at each interface as they pass through the slabs due to the change in refractive index, causing the emergent ray to be offset from the incident ray.
Why is the emergent ray parallel to direction of the incident ray in a rectangular glass slab?
In a rectangular glass slab, the emergent ray is parallel to the incident ray because of the principle of refraction. When light enters a denser medium (like glass) from a rarer medium (like air), it bends towards the normal. As the light exits the glass slab and reenters air, it bends away from the normal. The combination of these two refractions results in the emergent ray being parallel to the incident ray.
Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
When a light ray enters a rectangular glass slab at an angle, it bends towards the normal due to refraction. As it exits the glass slab, it bends away from the normal by the same amount due to refraction again. The angles at which the light ray enters and exits the slab are such that they cancel out the overall deviation, resulting in the emergent ray being parallel to the incident ray.
How can the lateral displacement of the emergent ray with respect to incident ray in glass slab be increased?
Lateral displacement increases if the: 1. Angle of incidence is increased. 2. Refractive index is increased 3. Thickness of the medium( i.e. here in your case the glass block) is increased.
Why incident ray and emergent ray are parallel to each other in the refraction of light?
Because both incident ray and emergent ray have same slope.
What is the relation between incident ray and emergent ray?
The incident ray is the ray of light that first strikes the surface of a medium or interface, while the emergent ray is the ray of light that exits the medium after being refracted or reflected. The direction of the emergent ray depends on the angle of incidence and the properties of the medium.

No, the incident ray and emergent ray will not be parallel if the glass slabs have different refractive indices. This is because the light rays will experience refraction at each interface as they pass through the slabs due to the change in refractive index, causing the emergent ray to be offset from the incident ray.
Why emergent parallel incident ray in a glass slab?
This is because the amount of refraction taking place at the parallel faces of a glass slab is equal but opposite and since the faces are parallel the emergent ray emerges parallel to the incident ray with lateral displacement.
Give simple detail of angle of deviation?

What is a glass slab?
it is a substance made of glass having 3 dimensions and is cuboid shaped. It does not deviate the light. This means that the incident and the emergent ray are parallel. The slab only produces lateral (sideways) shift or displacement.
What is emergent ray?

What is emergent ray in refraction of light?
The emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).

What is emergent angle?
Angle of emergence is the angle which the normal makes with the emergent ray.

Lateral displacement increases if the: 1. Angle of incidence is increased. 2. Refractive index is increased 3. Thickness of the medium( i.e. here in your case the glass block) is increased.
