Two speakers that are in phase output sound at a frequency of 825 Hz. The speakers are separated by 5.00 m, with one speaker at the origin and the other at (0, 5) m. Find points of totally destructive interference along the line y = 5, for x > 0. How do you get the points? I would have to use change in Points= (n+1/2)lamda but what do I put for L after inserting all the info? Thank you for all the help wavelength=23/55 (L-x)-x=n(23/55) L-2x=n(23/55) L-n(23/55)=2x x=L/2 -n(23/110) Now what do I put for the L ?
