2. The output from a pressure monitor mounted at a point (shown in figure below) along the path taken by a sound wave of a single frequency

2. The output from a pressure monitor mounted at a point (shown in figure below) along the path taken by a sound wave of a single frequency travelling at 343m/s through air with a uniform density of 1.21kg/m3. The vertical axis scale is set by ∆ps= 4.0mPa. If the displacement function of the wave is written as s(x,t)= smcos(kx-ωt) what are (a) sm (b) k (c) ω? The air is then cooled so that its density is 1.35 kg/m3 and the speed of a sound wave through it is 320m/s. The sound source again emits the sound wave at the same frequency and same pressure amplitude. What now are (d) sm, (e) k and (f) ω?
