Question

a speaker is mounted on a vertical pole at the same height asyour ear. a second speaker is mounted on the same pole, 3.0 m abovethe first speaker. these speakers transmit in phase a sound wave offrequency 460 Hz. Assume the speed of sound in air is 345 Hz. a) describe the interference you hear standing near thepole b) as you walk from the pole to a point that is 4.0 m from thebase of the pole, how many constructive interference maximums andhow many destructive interference minimums do you hear? a speaker is mounted on a vertical pole at the same height asyour ear. a second speaker is mounted on the same pole, 3.0 m abovethe first speaker. these speakers transmit in phase a sound wave offrequency 460 Hz.

Explanation / Answer

= 345/460 = 0.75
m, h = 3 m
path difference = 3 m = k, where k = 4, so it isConstructive interference
displacement = x = 4
path difference = (h2 + x2) - x= 5 - 4 = 1 m = 1.33
from x = 0 ( = 4) to x = 4 ( = 1.33),there're 2 constructive interference ( = 3 and2)
3 destructive interference ( = 3.5, 2.5,1.5)
