Refraction

Question 1

When a wave crosses a boundary between two materials what happens to the wave?

Answer 1

It changes speed

Question 2

What will happen to the wave if it is traveling along the normal?

Answer 2

It will change speed but it’s not refracted

Question 3

What happens to the wave if it hits a boundary at an angle?

Answer 3

it changes direction - it is refracted

Question 4

What happens to the wave if it bends towards the normal?

Answer 4

It slows down

Question 5

What happens to the wave if it bends away from the normal?

Answer 5

It speeds up

Question 6

What is the optical density of a material?

Answer 6

The measure of how quickly light can travel through it

Question 7

What happens to the wavelength of a wave if it is refracted?

Answer 7

it changes but the frequency stays the same

Question 8

What do ray diagrams show?

Answer 8

the path of a wave
