Waves - frequency, period, speed worksheet

Waves period, frequency and velocity
Name: ________________ Date: ___________
The period of a wave is the time it takes for one full wavelength. It is measured
in seconds (s) and has the symbol T.
The frequency of a wave is the number of waves per second. It is measured in
hertz (Hz) and has the symbol ๐‘“.
Period and frequency are inversely proportional to each other (reciprocals).
That means as one increases the other decreases and vice versa. As a formula:

1) Find the amplitude of P, Q and R.
2) Find the period of P, Q and R.
3) Calculate the frequency of P, Q and R.
The velocity of a wave is how fast the wave is travelling. It is measured in
metres per second (m/s) and has the symbol v.
The wavelength of a wave is the distance between two corresponding points in
a wave, usually taken from crest to crest or trough to trough. It is measured in
metres (m) and has the symbol ๐œ† (lambda).
The wave equation describes the relationship between velocity, frequency and

4) Find the wavelengths for P, Q and R above if their velocities are 100 m/s.
5) Find the amplitude and wavelength of the above wave.
6) If it took 10 seconds for the above wave to pass, calculate its period,
frequency and velocity.
