the length travelled by a wave in one second.

Detailed explanation-1: -The number of complete waves produced in one second, or the number of vibrations/oscillations of the sound wave travelling through medium per second is called frequency of the wave. The SI unit of frequency is hertz (Hz).
Detailed explanation-2: -Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.
Detailed explanation-3: -It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. Hertz (Hz) = One hertz is equal to one cycle per second. Cycle = One complete wave of alternating current or voltage.
Detailed explanation-4: -The frequency of a wave is the number of times per second that the wave cycles. Frequency is measured in Hertz or cycles per second. The frequency is often represented by the lower case “f.” The period of the wave is the time between wave crests.
