Why is the angle of refraction zero in newton's ring exp?
The angle of refraction is zero in Newton's ring experiment because the incident light is perpendicular to the plane of the glass plate, so refraction does not occur. This allows for constructive interference between the incident and reflected light waves, leading to the formation of interference rings.
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.
To make the smaller glass disappear that is make it appear to be invisible How would the index of refraction of the liquid inside have to compare to the index of refraction of the glass?
If you want the smaller glass to appear invisible in the liquid it contains, the index of refraction of the liquid must be equal to or very close to the index of refraction of the glass. Matching these refractive indices results in minimizing the reflection and refraction of light at the glass-liquid interface, making the glass less visible to the observer.
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.
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 angle of refraction zero in newton's ring exp?
The angle of refraction is zero in Newton's ring experiment because the incident light is perpendicular to the plane of the glass plate, so refraction does not occur. This allows for constructive interference between the incident and reflected light waves, leading to the formation of interference rings.
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.
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 does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
