Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m to the right of speaker A. The frequency of the sound waves produced by the loudspeakers is 206 Hz. Consider Point P between the speakers and along the line connecting them, a distance x to the right of speaker A. Both speakers emit sound waves that travel directly from the speaker to point P.
a) For what values of x will destructive interference occur at point P?
b) For what values of x will constructive interference occur at point P?
Assume we have an infinitely long wire carrying a current of 2-A. It is bent into an L-shape extending into positive infinities along the x- and y- axes. Find out the magnitude of the magnetic field at a point P with coordinates (0.3 m, 0.3 m).
