Q
2) What is the amplitude?
A
The displacement from the rest position to the crest (not from a trough to a crest)
1
Q
1) Waves have a ….. , ….. and …..?
A
Amplitude, wavelength and frequency
2
Q
3) What is the wavelength?
A
The length of a full cycle of the wave, e.g. from crest to crest
3
Q
4) What is the frequency?
A
The number of complete cycles or oscillations per second
4
Q
5) What is frequency measured in?
A
Hertz (Hz) (1 Hz = 1 wave per second)
5
Q
6) What is the formula for wave speed?
A
Wave speed (m/s) = frequency (Hz) x wave length (m)

Q
7) What are the standard units of measure used in wave equations?
A
- Metres
- Seconds
- M/S
- Hertz (Hz)
