Remember that the speed of a wave is the product of both the wavelength and the frequency of the wave.

First convert the units to m and then multiply the values to calculate its propagation or wave speed.

C = lambda • frequency.

Wave speed = wavelength* frequency
(M/s). (M). (Hz)

8mm-0.008m

0.008m*4Hz=
Wave speed = 0.032m/s
