An air-filled standing wave tube is terminated with an unknown specific acoustic

An air-filled standing wave tube is terminated with an unknown specific acoustic impedance Z. At a frequency of 1143HZ the SWR is 1.4. As the distance d from the terminated is increased, the pressure amplitude increases monotonically until it reaches a maximum at d=0.05m. Find the following. (a) Wavelength (b) Reflection coefficient R (in polar form R=pe) (c) Impedance Z, (Real and imaginary parts)
