Plane
sound wave reflection and transmission between two fluid media:
-
Interface is at x=0.
Fluid in x<0 region is sea water (c1=1500 m/s, rho1=1026 kg/cu.m)
-
Fluid in region x>0
is slow bottom (c2/c1=0.9, r2/r1=0.9). (corresponds to K&F Fig.
6.4.2)
-
Frequency is 2 kHz,
and angle of incidence is 60 degrees.
-
Maximum positive pressure
is blue, and minimum (negative) pressure is red; zero pressure is blue/green
(the B&K color!)
