Wave Basics

HideShow resource information
What is the amplitude?
The amplitude is the displacement from the rest position to the crest (top of a wave)
1 of 11
What is the wavelength?
The wavelength is the length of a full cycle of the wave ( e.g. from crest to crest)
2 of 11
What is the frequency?
The frequency is the number of complete waves passing a certain point per second OR the number of waves produced from a source each second
3 of 11
What is frequency measured in?
Frequency is measured in hertz (Hz). 1 hertz is 1 wave per second
4 of 11
Which direction are the vibrations in transverse waves?
In transverse waves, the vibrations are perpendicular to the direction of energy transfer of the wave
5 of 11
Which direction are the vibrations in longitudinal waves?
In longitudinal waves, the vibrations are parallel to the direction of energy transfer of the wave
6 of 11
What are some examples of transverse waves?
1. Light and all EM waves 2. Ripples on water
7 of 11
What are some examples of longitudinal waves?
1. Sound waves and ultrasound 2. Shock waves (e.g. seismic waves)
8 of 11
Which type of wave has evenly spaced vibrations?
Transverse waves
9 of 11
Which type of wave has compressions and rarefactions?
Longitudinal waves
10 of 11
What is the formula for wave speed?
speed (m/s) = frequency (Hz) x wavelength (m)
