Question

a longitudinal wave travels at the speed of 0.3m/s and the frequency of a wave is 20Hz find the separation between the two consecutive compressions​

Answer 1

wave velocity = 0.3m/s

frequency= 20Hz

wave velocity= frequency × wavelength

so, wavelength= wave velocity/ frequency

= 0.3/20

lemda= 1.5 × 10^-2 m

hope it helps u
