1) (I have to apologize in advance for my lack of creativity and resulting re-use of this problem.) This problem gets to a quantitative analysis of the \"walkaround demo\" done on the second day of class. The actual setup used was slightly different, but this combination of parameters also has interesting output. ---------------------------------------- ---------------------------------------- Take the speed of sound in the room as 340 m / s. The speakers (\"8\" in the gure) are 3m apart and emit the same frequency. There are two observation points, 'P, 4m directly in front of one of the speakers, and C, along the center line between the speakers, also 4m out. a) [a pure ond not too diicult geometry problem] Calculate the distance from each speaker to each observation point. b) At the point C, when the speakers are in phase (that is: no phase difference), is there constructive or destructive interference? What about when the speakers are 180 out of phase? c) Suppose the tone emitted is 340 Hz and the speakers are in phase. d) Describe what happens when the emitted sound from the speakers is 170 Hz instead of 340 both for the in phase and out of phase cases at each point
