Waves
transfer energy from one place to another.
Mechanical waves
require a matter to move energy.
The matter will move for a short period of time whilst transferring energy and then return to its starting position.
Transverse waves
particles move perpendicular to the motion of the wave
e.g: water ripples, EM waves

Longitudinal waves
particles move parallel to the motion of the wave
e.g: sound waves

Period of a wave (s)
how long it takes to go through one wavelength

Frequency (Hz)
how many wavelengths go by in a second

Wavelength (m)
the distance between one crest of a wave and the next crest or trough to trough or from one point of the wave to same point of the next wave.
Wavelength vs period
period measures the wave in time
wavelength measures it in space
Amplitude of a mechanical wave
the maximum displacement of the particles in the wave.
the distance from the rest point.
the greater the amplitude of the mechanical wave, the greater the energy.
