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.
What else can I help you with?
The incident ray and the emergent ray will always be?
The Incident ray, falling on the glass slab, and the Emergent ray will always be parallel to each other.
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.
How is an incident ray related to a reflected 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.
what is the angle between the incident ray and the normal are called?
The angle between the incident ray and the normal is called the angle of incidence.
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.
Give simple detail of angle of deviation?
The angle Between the path of incident ray and emergent ray
The incident ray and the emergent ray will always be?

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.
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.
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.
How is an incident ray related to a reflected 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.

what is the angle between the incident ray and the normal are called?
The angle between the incident ray and the normal is called the angle of incidence.
What is the difference between incident ray and the reflected ray?
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.
A reflected ray in a mirror makes an angle of 20 and deg with the incident ray. when the mirror is rotated 15 and deg what angle will the reflected ray now make with the incident 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.
