An instrument measures a repeating wave pattern. It records that 20 complete cycles of the wave pass a specific point over a period of 4 seconds. What is the frequency of this wave?

Hertz (Hz) is the standard unit of measurement for frequency, representing the number of cycles or waves that pass a given point per second.

Frequency is defined as the number of waves that pass a specific point in a given period of time. There is an inverse relationship between a wave's frequency and its wavelength; longer wavelengths correspond to lower frequencies, while shorter wavelengths are associated with higher frequencies.
