Intro

Question 1

What is refraction of light?

Answer 1

The bending of light due to change in the speed when it travels from one medium to another

Question 2

Things observed in Rarer medium

Answer 2

Optical density is less
Speed of light is more
Light travels faster

Question 3

Things observed in Denser medium

Answer 3

Optical density is more
Speed of light is less
Light travels slower

Question 4

Any one effects caused by the Refraction of light

Answer 4

An object placed under water appears to be raised
A pool of water appears to be less deep than it actually is

Question 5

Why does a ray of light bends when it travels from one medium to another

Answer 5

Due to the change in speed

Question 6

What is Angle of Incidence?

Answer 6

The angle between incident ray and the normal in the point of intersection is known as the Angle of Incidence

Question 7

What is Angle of Refraction?

Answer 7

The angle between refracted ray and the normal in the point of intersection is known as the Angle of Refraction

Question 8

What is Angle of Emergence?

Answer 8

The angle between emergent ray and the normal is know as the Angle of emergence

Question 9

When does the ray bend towards the normal

Answer 9

When a ray of light goes from Rarer to Denser medium

Question 10

When does the ray bend away from the normal

Answer 10

When a ray of light goes from Denser to Rarer medium

Question 11

What is Lateral Displacement?

Answer 11

The perpendicular distance between the original path of the incident ray and the emergent ray coming out of a glass slab is called Lateral Displacement
