Refraction Flashcards
1
Q
When a wave crosses a boundary between two materials what happens to the wave?
A
It changes speed
2
Q
What will happen to the wave if it is traveling along the normal?
A
It will change speed but it’s not refracted
3
Q
What happens to the wave if it hits a boundary at an angle?
A
it changes direction - it is refracted
4
Q
What happens to the wave if it bends towards the normal?
A
It slows down
5
Q
What happens to the wave if it bends away from the normal?
A
It speeds up
6
Q
What is the optical density of a material?
A
The measure of how quickly light can travel through it
7
Q
What happens to the wavelength of a wave if it is refracted?
A
it changes but the frequency stays the same
8
Q
What do ray diagrams show?
A
the path of a wave
