Unformatted text preview: d opposite to the force of fluid 2 on fluid 1. Use this condition
to find a second equation relating R and T. Write this equation in terms of the
impedances Z1 and Z2. (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?
