How do you measure longitudinal waves?

Asked by: Christina Newman
The wavelength can always be determined by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.
How is longitudinal amplitude measured?
The wavelength can be measured as the length between two consecutive crests or two consecutive troughs of a waves you'll notice that here by measuring between two consecutive troughs.
What is frequency measured in?
hertz (Hz)
The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.
What instrument measures frequency?
frequency meters
frequency meter, device for measuring the repetitions per unit of time (customarily, a second) of a complete electromagnetic waveform. Various types of frequency meters are used.
Which instrument measure the frequency of electromagnetic waves?
wavemeter
wavemeter, device for determining the distance between successive wavefronts of equal phase along an electromagnetic wave. The determination is often made indirectly, by measuring the frequency of the wave.
