Homework Statement
Two loudspeakers emit sound waves along the x axis. Speaker 2 is 2.0 m behind speaker 1. Both loudspeakers are connected to the same signal generator, which is oscillating at 340 Hz, but the wire to speaker 1 passes through a box that delays the signal by 1.47 ms.
Is the interference along the x-axis perfect constructive, perfect destructive or something in between?
Homework Equations
The Attempt at a Solution
340 m/s = (340 Hz) * [tex]\lambda[/tex]
[tex]\lambda[/tex]= 1.0 m
First, turning to the formula deltaphi= 2pi * (deltax/wavelength)
plugging in the values delta phi = 2pi*(2.0m/1.0 m) = 4pi
and so I came up with perfect constructive.
Is this correct? I am trying to think about how the delay would affect the interference of the waves, so if anyone could offer a good explanation of why the delay does or does not affect the superposition, I would greatly appreciate it.
Thanks
