1
Q
Mechanical waves
A
Waves that require a medium to travel through, water and seismic waves
2
Q
Electromagnetic waves
A
Waves that can travel through a vacuum
3
Q
Transverse waves
A
A wave in which the particles move at right angles to direction of energy transfer
4
Q
Longitudinal wave
A
A wave in which oscillation of the particles is in the same direction
5
Q
Wavelength
A
This is the distance from a point on one wave to the same point on the next wave
6
Q
Frequency
A
This is the number of waves passing a point every second and is measured in hertz
7
Q
Amplitude
A
The height of the wave from the centre line to a peak or trough
8
Q
Wave formula
A
Wave speed = frequency times wavelength
