Question

what is the time period of a sound wave?

Answer 1

f = c / λ = wave speed c (m/s) / wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency). λ = c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.

Answer 2

the time taken to complete one vibration or one complete wave is called time period of the wave.

hope it helps pls......mark it as brainliest
