A sound wave of velocity 600 m/s has a wavelength of 3 m. At a certain instant one of the molecules of the medium is at its normal position. How long will it be before this same molecule is again at its normal position?
v=fλ, f=v/λ =(600m/s)/3m = 200Hz
T=1/f=1/200=.005s
t=T/2 = .0025s Is this answer correct?
Thanks
