A simple harmonic progressive wave in a gas has a particle displacement of y=a at time `t=T//4` at the orgin of the wave and a particle velocity of y =v at the same instant but at a distance `x=lambda//4` from  the orgin where T and `lambda` are the periodic time and wavelength of the wave respectively. then for this wave.
