Wave
* A disturbance propagating through a medium.
* Disturbance- a pattern of displacement from an equilibrium point or state
* Propagation- self sustaining motion
* Disturbance- a pattern of displacement from an equilibrium point or state
* Propagation- self sustaining motion

11
New cards
Transverse Waves
Particles in the medium oscillate in SHM __perpendicular__ to the direction in which the wave disturbance moves.
12
New cards
Longitudinal Waves
Particles in the medium oscillate in SHM parallel to the direction in which the wave disturbance moves.
13
New cards
Wavelength
Crest to crest
14
New cards
Trough
Lowest point/crest on graph
15
New cards
Crest
Highest point on graph
16
New cards
Amplitude
Distance from equilibrium to trough or crest.
17
New cards
Compression
When particles are compressed together
18
New cards
Rarefaction
When particles are far apart
19
New cards

have compressions and rarefactions
20
New cards
Raleigh Waves
Particles move in elliptical paths
21
New cards
Torsional Waves
