(The pressure associated with the displacement wave is Δp = p p0 = -B ds/dx.) (c) Solve the two equations found in (a) and (b) to find R and T in terms of the impedances of the two media. (d) The densities of air and water are 1.2 kg/m3 and 1000 kg/m3, and their bulk moduli are 1.42 x 105 Pa and 2.2 x 109 Pa. What are the wave speeds v and characteristic impedances Z of air and water? Physics 2214, Spring 2012 3 Cornell University (e) Suppose that a sound wave is incident from air normal to an air-water interface. What will be the amplitude of the wave that is transmitted into the water, relative to the incident amplitude? Is your result consistent with your experience? 6.
