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=1.1). (corresponds to K&F
Fig. 6.4.3)
Frequency is 2kHz,
and angle of incidence is 46.4 degrees (INTROMISSION ANGLE).
Maximum positive
pressure is blue, and minimum (negative) pressure is red; zero pressure
is blue/green (the B&K color!)
