Physics

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

a) Draw time graphs for both speakers' oscillations when thefrequency is 500 Hz.
b) Determine the three lowest frequencies that give completeconstructive interference in the point
c) Determine the three lowest frequencies that give completedestructive interference in point P.
