The number of wave crests passing a point in one second
3 of 16
What is the wavelength of a wave?
The distance from one wave crest to the next wave crest
4 of 16
What is the difference between transverse and longitudinal waves?
Transverse wave - oscillations are perpendicular to the direction of energy transfer Longitudinal - oscillations are parallel to the direction of energy transfer
5 of 16
What do waves transfer?
Energy and information
6 of 16
What do waves not transfer?
Matter
7 of 16
What does a greater amplitude of a wave mean?
That it transfers more energy
8 of 16
What does refraction of a wave do?
It changes the direction and speed of a wave at the boundary
9 of 16
What is diffraction of a wave?
The spreading of waves when they pass through a gap or move past an obstacle
10 of 16
When is diffraction most noticable?
When the hole is the same size as the wavelength of the wave
11 of 16
What is interference?
The reinforcement or cancellation of waves when two identical sets of waves overlap
12 of 16
What happens when a crest meets a trough?
The two waves cancel each other out
13 of 16
When does reinforcement occur?
Whenever the difference in the distances to each slit is a whole number of wavelengths
14 of 16
When does cancellation occur?
Whenever the difference in the distances to each slit is a whole number of wavelengths + an extra half wavelength
