Which term refers to the number of cycles per unit time?

Explanation:
Frequency is the rate at which cycles occur per unit time. It tells you how many times the wave repeats each second, and the standard unit is hertz (Hz), meaning one cycle per second. So a frequency of 440 Hz means 440 cycles pass a point each second. This concept is distinct from wavelength (the spatial distance between crests), amplitude (how tall the wave is), and speed (how far the wave travels per unit time). Remember, wavelength and frequency are related through speed, since speed can be the product of frequency and wavelength, but frequency itself specifically measures cycles per time.
