Question

A sound wave of frequency 660Hzincidents normally on a perfectly
reflecting object If the speed of sound on air is 330 m
s-1,then what is the shortest distance from the wall at
which the wave particles have

the maximum displacement
the minimum displacement

Ved Prakash Lakhera · Accepted Answer

Given frequency  f = 660 Hz,  V = 330m/s
Formula of sound wave velocity    V = f×λTherefore    λ = Vf=330660=0
5 m1
  The distance from the wall where displacement of the wave is maximumis λ/2 =0
5/2=0 25m=25cm  2
  The distance where displacement of the wave is minimum is      λ = 0
5m=50cm
