A wave's frequency is the number of cycles that are completed in a certain amount of time. The symbol for frequency is the lowercase f and we measure it in cycles per second, which is the same as the unit hertz. A wave with a frequency of 20 Hz completes 20 wave cycles every second.Be careful that you don't confuse frequency with period. This is a common mistake. wave is a disturbance that travels through a medium in a periodic fashion, carrying energy without transporting matter. Waves are described and measured by five wave parameters: the period, the frequency, the amplitude, the wavelength, and the speed.
