Refraction

Question 1

In class we learnt about Refraction, and its application to light.

What causes Refraction?

Answer 1

The cause is a change in the density of a medium the wave passes which (causes change in wave speed)

Question 2

In class we learned about the Index Of Refraction.

We used the angle of incidence and the angle* of refraction to do so.

What is the symbol of Index Of Refraction and the equation to calculate that specific value

Answer 2

“n” is the symbol of index of refraction.

the equation of index of refraction is:
n=sin(i)/sin(r)

Question 3

Refraction occurs due to a?

Answer 3

change in wave speed

Question 4

First ray that is going to enter the denser medium is called the?

Answer 4

incident ray.

Question 5

the line drawn at 90*c to the surface where the ray enters medium is called…?

Answer 5

Normal line.

Question 6

The second ray that is moving between the denser medium

Answer 6

Refracted ray.

Question 7

The ray that has left the denser medium and returned back to normal speed

Answer 7

Emergent ray.
