Refraction
Karten in diesem Stapel (6)
- 1What is refraction?Refraction is waves changing at a boundary. When a wave crosses a boundary between materials at an angle it changes direction.
- 2What affects how much a wave is refracted?How much the wave speeds up / slows down.
The density of the two materials. - 3What happens if a wave crosses a boundary and slows down?It will bend towards the normal.
- 4What happens if a wave crosses a boundary and speeds up?It will bend away from the normal.
- 5What happens to the frequency, speed and wavelength as it is refracted?The wavelength will change but the frequency will stay the same. If the wave is travelling along the normal it will change speed, but it will not be refracted.
- 6What is the optical density of a material?A measure of how quickly light can travel through it. The higher the optical density, the slower light waves can travel through it.
