Physics Flashcards
1
Q
What is refraction
A
Refraction is the change in direction of a wave at the boundary between two materials
2
Q
When a wave can travel from one material to another what can it do
A
It can change direction
3
Q
What are the rays
A
Rays are straight lines that point along the direction of the wave is moving at
4
Q
What is the normal line
A
It is an imaginary line that’s perpendicular to the boundary
5
Q
What is the angle of incidence
A
Angle of incidence is the angle between the incoming ray and the normal
6
Q
What is the angle of refraction
A
Angle of attraction is the angle between the refracted ray and the normal
7
Q
What happens if the wave hits the boundary at 90 degrees
A
The wave won’t change direction
8
Q
What happens if the wave hits the boundary at any other angle
A
It will change direction
