One speaker A is located at the origin and another speaker B, is located at the point (3.0), the units
in the xy plane is measured in meters and the speakers are the same. At a point P = (1,4) a microphone is placed.
The speakers are connected to a tone generator that generates sine tones (flat waves) so that speaker
B is ? / 4 after A in phase and the sound speed is 350m / s.

a) Draw time graphs for the oscillations of both speakers when the frequency is 500 Hz. State clearly
what form of wave function you use.

b) Determine the three lowest frequencies which give complete constructive interference in point P.

c) Determine the three lowest frequencies which give complete destructive interference in point P.
