Since there are several kinds of waves, there are several ways to measure their frequency.
Electrical waves can be measured with a frequency counter, an analog frequency meter or an oscilloscope.
Ocean waves' frequency is measured with a stopwatch, but most people who measure ocean waves want to know how large they are rather than how fast they're coming.
To measure the speed of a wave, you multiply the frequency by the wavelength.
frequency
Hertz is used to measure the frequency of a wave, which represents the number of complete wave cycles that occur in one second.
The equation used to measure wave speed is: Wave speed = frequency x wavelength
You will have to measure it.
The frequency expresses how many complete cycles of the wave pass a certain point every second.
wave frequency.
How many oscillations per second
The unit of measure for the frequency of a sound wave is hertz (Hz), which represents the number of cycles or vibrations per second.
Hertz means cycles per second. That is its' frequency.
A wave can have any frequency, not just one Hertz.
Short wave frequency has a shorter wave length. Frequency is defined as number of cycles per second. If you have shorter waves (measure from peak to peak) you can get more of these packed into one second, so the frequency is higher.
