New cards
Refraction
When light waves change direction at the boundary between two transparent materials
2
New cards
Incident ray
The incoming ray that hits the boundary between the two materials
3
New cards
Angle of incidence
The angle between the incident ray and the normal line
4
New cards
Refracted ray
The ray that changes direction after passing through the boundary between the two materials
5
New cards
Angle of refraction
The angle between the refracted ray and the normal line
6
New cards
Effect of density on the speed of a wave
The denser the transparent material, the more slowly the wave travels through it
7
New cards
What happens to speed when light enters a more dense material
The light ray slows down and bends towards the normal line
8
New cards
What happens to speed when light enters a less dense material
The light ray speeds up and bends away from normal line
9
New cards
Effect of density on the wavelength of a wave
The denser the transparent material, the more slowly the wave travels through it so the wavelength decreases
10
New cards
Effect of density on the frequency of a wave
The frequency of a wave is unaffected
