In a 12m wide and 16m long classroom, there's two speakers mounted 4m apart on one of the shorter walls. Because of the large size of the classroom, the ceiling needs a few support columns. Your boss has decided to place the columns somewhere on the dashed lines in the diagram in the spots where there would have been destructive interference between the speakers. Calculate all the places on those lines where the columns could be located, assuming a sound frequency of 500 Hz and a speed of sound of 330 m/s in the room. ignore the effect of echoes.

Imagine you are in an open field where two loudspeakers are set up and connected to the same amplifier so that they emit sound waves in phase at 688 HzHz. Take the speed of sound in air to be 344 m/sm/s. What is the shortest distance d you need to walk forward to be at a point where you cannot hear the speakers? The forward direction is defined as being perpendicular to a line joining the two speakers and you start walking from the line that joins the two speakers.

A speaker, speaker A, is 2.00 m in front of you playing a single frequency 35.00Hz.* A second speaker, speaker B, is placed behind speaker A, further from you and along the line from you to speaker A. The speaker B plays the same frequency and the difference in phase constant between the two speakers is Δ øo = π /2. a) At what distance from you, further than the first speaker, do you need to place the second speaker so that there is total deconstructive interference, amplitude zero at all times, at your location? Assume 20 oc. There are a discrete set of infinite answers and I will accept any of them.
