Is incident ray parallel to the emergent ray through two glass slab of different refractive index?
Wiki User
∙ 11y ago
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.

The incident ray and the emergent ray will always be?
The incident ray and the emergent ray will always be parallel when light passes through a parallel-sided transparent medium like a glass block or a prism.
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.
What is the mirror that causes parallel incident rays of light to converge at the focus?
The mirror that causes parallel incident rays of light to converge at the focus is a concave mirror. This type of mirror is curved inward and has a reflective surface that causes light rays to converge towards a focal point when they strike the mirror parallel to its principal axis.
What is An incident ray that passes through the focal point of a lens?
An incident ray that passes through the focal point of a lens will emerge parallel to the principal axis. This is a property of convex lenses.

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 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 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 the angle between a reflected and a refracted rays when a light ray is incident at 30 degrees on a parallel block of thickness 5cm and refractive index 1.5?
Light will be reflected at an angle of 30deg from the normal. We can work out the angle of refraction using the formula: n(1) sin(incident angle) = n(2) sin(refracted angle) We will assume the refractive index given is the relative refractive index n(2)/n(1). So sin(30)/1.5 = sin(r) r = 19.5 deg As the reflectedd and refracted rys are on the same side of the normal we can subtract them from 180 to get the angle between them: 180 - 19.5 - 30 = 130.5
Why should the ray emerging from the glass block come out parallel to the incident ray?
The ray comes out parallel to the incident ray because the ray has the opposite refraction as when it entered the block.
What is optical center of lens?
The optical center of a lens is a point on the lens axis where light passing through the lens does not deviate, regardless of the angle of incidence. It is often used as a reference point for optical calculations and design. The optical center is typically at the geometric center of a lens with a symmetrical shape.
What is the mirror that causes parallel incident rays of light to converge at the focus?
The mirror that causes parallel incident rays of light to converge at the focus is a concave mirror. This type of mirror is curved inward and has a reflective surface that causes light rays to converge towards a focal point when they strike the mirror parallel to its principal axis.
When is the angle of incidence in the greatest?
Angle of incident is greatest when the light rays is almost parallel to the surface it hits.
