4.1 Waves - Properties of Waves
Velocity (v)
The rate that the wave travels
Determined by frequency and wavelength
v = fλ
Period (T)
Time taken for a complete wave to pass a given point
f = 1/T
Frequency is the reciprocal of period
Frequency (f)
Number of waves that pass a given point in a second
Measured in Hertz (Hz)
1 Hz = 1 wave each second
Wavelength (λ)
Distance from one point to the same point of the adjacent wave
Peak-peak or trough-trough is often used
Measured in metres
Wavefront
A line where all the oscillations of the wave are in phase (all at the same position in their cycle)
Water Waves
A float on water will bob up and down when a wave passes
The wave is transferred but the medium is not
can have characteristics of both transverse and longitudinal waves
Waves transfer energy and information, not matter
Amplitude
Maximum displacement of a wave from its rest position
For sounds, amplitude determines the volume of the sound
