Question

wha do you mean by a sound of frequency 20 Hertz. what will be the time period of this sound​

Answer 1

Answer:

For example, a sound wave with a frequency of 20 hertz would have a period of 0.05 second (i.e., 20 wavelengths/second × 0.05 second/wavelength = 1), while a sound wave of 20 kilohertz would have a period of 0.00005 second (20,000 wavelengths/second × 0.00005 second/wavelength = 1).
