Question

what is frequency of sound​

Answer 1

Answer:

Frequency is the measurement of the number of times that a repeated event occurs per unit of time. The frequency of wave-like patterns including sound, electromagnetic waves (such as radio or light), electrical signals, or other waves, expresses the number of cycles of the repetitive waveform per second.

Answer 2

Answer:

— Frequency, sometimes referred to as pitch, is the number of times per second that a sound pressure wave repeats itself. ... The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz. Frequencies above 20,000 Hz are known as ultrasound.
