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.
The Incident ray, falling on the glass slab, and the Emergent ray will always be parallel to each other.
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.
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.
The relation between the incident ray and reflected ray is described by the material which is reflecting the incident ray. depending upon the material used the incident ray is scattered or reflected or refracted or transmitted or absorbed. For example if you take rainbow the sun light is incident on the rain drop , it reflected back of drop several times and due to that we get the rainbow with various colours.
The angle between the incident ray and the normal is called the angle of incidence.
Because both incident ray and emergent ray have same slope.
The angle Between the path of incident ray and emergent ray
The Incident ray, falling on the glass slab, and the Emergent ray will always be parallel to each other.
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.
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.

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.
The relation between the incident ray and reflected ray is described by the material which is reflecting the incident ray. depending upon the material used the incident ray is scattered or reflected or refracted or transmitted or absorbed. For example if you take rainbow the sun light is incident on the rain drop , it reflected back of drop several times and due to that we get the rainbow with various colours.

The angle between the incident ray and the normal is called the angle of incidence.
incident ray-the light ray striking a reflecting surface is called the incident ray. reflected ray-the light ray obtained after reflection from the surface, in the same medium in which the incident ray is travelling , is called the reflected ray.
The angle between the incident ray and the reflected ray is equal to the angle between the incident ray and the normal. When the mirror is rotated, the normal also rotates by the same angle. Therefore, the angle between the incident ray and the reflected ray will still be 20 degrees.
