Superposition
of a plane wave and a spherical wave:
-
Fluid is ambiant air.
The plane wave travels from left to right (in positive-x direction).
-
Spherical wave emitted
at the origin by pulsating sphere of radius a=5 cm.
-
The frequency is 2000
Hz. Both waves have unit complex amplitudes, and are perfectly synchronous.
-
Maximum positive pressure
is blue, and minimum (negative) pressure is red; zero pressure is blue/green
(the B&K color!)
