Answer:
The total number of waves produced in one second is called the frequency of the wave. The number of vibrations counted per second is called frequency. Here is a simple example: If five complete waves are produced in one second then the frequency of the waves will be 5 hertz (Hz) or 5 cycles per second.

Answer:
Frequency, sometimes referred to as pitch, is the number of times per second that a sound pressure wave repeats itself. ... High frequencies produce more oscillations. The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz.
