What are the terms related to refraction of light?
terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation
Is there a distinction between light reflection and light refraction?
When a ray of light strikes an obstacle it changes its path this is called reflection of light whereas the bending of light ray while traveling from one medium to other is called refraction.
What is the ray diagram of light refraction in air and glass?
A prism
Which property of light ray does not change in refraction?
Frequency remains same.
What happens when a light moves from a material with a lower index of refraction to another material with a higher index of refraction?
The ray of light bends towards the normal.
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.
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.
How do you explain that the pencil appears broken in the glass of water?
A ray of light changes direction when it gets out of the water, and into the air. This is called "refraction".A ray of light changes direction when it gets out of the water, and into the air.

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
Why does the light ray bend?
due to the phenomenon of refraction .
Is there a distinction between light reflection and light refraction?
When a ray of light strikes an obstacle it changes its path this is called reflection of light whereas the bending of light ray while traveling from one medium to other is called refraction.
Which property of light is illustrated when the ray enters the pond?
refraction
What is the ray diagram of light refraction in air and glass?
A prism
When does total internal refraction happen?
Total internal refraction happens when a light ray travel from a lighter medium to a denser medium. Ex. A light ray passing through a Prism.
What is the bending of light rays caused by a change in speed of the light ray called?
Refraction
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
