shown below. They are both emitting sound at 85 [Hz] with equal amplitude, but the upper speaker has a phase shift of -\ pi/4 radians compared to the lower speaker. Use 340 m /s for the speed of sound. a) As you walk away from the lower speaker (in the direction of the arrow), starting from right in front of it, how far away from the lower speaker do you first encounter a point of perfect destructive interference? b) Find the next point of destructive interference. c) Finally, find the 3rd point of perfect destructive interference. Are these points evenly spaced? Note: most of the points in this problem come from correctly setting it up. Draw a picture and neatly show your work.
