Why the ray of light bends away normal or towards normal when it passes from one medium to another?
it deviates its path and meet where water and air surfaces meet.
What is refraction ray?
A refracted ray passes through the medium, at a different angle to the normal than the incident ray. by Ronan Lavery
How do you compare reflection refraction and dispersion?
You can compare it by saying that each of them occur when a light transfers through one meduim to another. That's one way of explaining it.That is incorrect :( It happens when light is shone onto or through a different medium. Reflection happens when light is shone ONTO a mirror, you cant shine light THROUGH a mirror.
Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
The glass slab is rectangular and both sides of the glass slab have the same medium. The light refracts in such a way that incident and emergent rays are parallel.
Which light is called the incident ray?
To be Specific, It would be the ray of light which is moving towards the medium.

How the thickness of the atmosphere affects how light is bent?
when light travels from one medium to another it deviates from its normal path. the deviation is dependent on the refractive index of the medium. Bending of light ray also depends on the thickness of the medium. therefore more the thickness more is the deviation caused and more is the bending.
What are the similarities of reflection and refraction?
REFLECTION: IF a light ray in incident on a surface if it bring back to same medium is called reflection REFRACTION: IF a light ray in incident on a surface and going to another medium is called reflection and there is a a law for refraction that is SNELL'S LAW
In what situation does a wave not change its direction when it passes from one medium into another?
Waves only change direction when they intersect the other medium at an incident angle of other than 90o

What is another word for the substance in which a wave travels?
A medium.
Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
The glass slab is rectangular and both sides of the glass slab have the same medium. The light refracts in such a way that incident and emergent rays are parallel.
Would you be able to observe the refraction of light if the incident light were perpendicular to the medium?
No, you wouldn't be able to.
Which light is called the incident ray?
To be Specific, It would be the ray of light which is moving towards the medium.
How to derive lateral shifting formula?
When a ray of light from a medium is incident on another medium with different optical density, the ray bends due to refraction. The perpendicular distance between the emergent ray and the incident ray is called the lateral shift. The angle which the incident ray makes with the normal is called angle of incidence denoted by 'i' and the angle made by the refracted ray with the normal is called the angle of refraction denoted by 'r'. Lateral shift is given by the formula:- Where t is the thickness of the glass slab, i is the angle of incidence and r is the angle of refraction
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.
