What does a wave do?
Transfers energy from one place to another
Oscillation
Repeated movement of a particle about a fixed point
Longitudinal wave
Wave where oscillations are parallel
Transverse wave
Wave where oscillations are at 90* (right angle)
Mechanical wave
Travels through a medium (solid, liquid or gas)
Crest/peak
Top of the wave
Trough
Lowest point of the wave
Amplitude
Vertical distance from center line and peak/trough
Wave speed=
Frequency x wave length
