Answer:
the separation between the two consecutive compressions is termed as WAVE LENGTH.
Wave speed:- 18km/h = 5m/s
Frequency:- 0.5khz = 500hz
Formula:-
Wave speed = Frequency × Wavelength
5 = 500 * Wavelength
Wavelength = 5/500 = 1/100 = 0.01 metre.
the separation between the two consecutive compressions is 0.01 metre or 1cm.
