A student enters Best Buy prepared to buy a pair of speakers. Before he does, he conducts an experiment with them. He places them 4.0 m apart and then connects a signal generator to both speakers that produces a single tone of 240 Hz. He then walks in front of the speakers so that he is 2.0 m from one speaker and 5.0 m from the other. If the speed of the sound in the room is 360 m/s, will he be standing in a “quiet” spot? Explain.
Homework Answers
Concept: find the wavelength and then the path difference. This shows that path difference corresponds to constructive interference.

Q3M.1 You are setting up a pair of PA speakers on a field in paration for an outdoor event. Each speaker is 0.65 m wide, and the speakers are separated by 8.2 m. To test the speakers, your coworker plays a single tone through the speakers whose frequency is 440 Hz. You are standing 52 rm directly in front of the speakers and facing them.

Two identical speakers (labeled 1 and 2) are playing a tone with a frequency of 225 Hz, in phase. The centers of the speakers are located 6.00 m apart. Five observers are standing on a line that is 6.00 m in front of the speakers as shown in the figure. Each observer is separated by 1.00 m and Sue is directly in front of speaker 1. Determine which observer or observers will experience constructive interference from the sound emitted by...

Two speakers, 1 and 2, are set up with their centers 6.00 m apart. Both are playing the same tone of frequency 225 Hz, in phase. Five listeners are standing on a line that is 6.00 m in front of the speakers as shown in the figure. Each listener is separated by 1.00 m and Cal is directly in front of speaker 1.

You are standing a distance d
(2m) directly in front of one of two identical speakers, being
driven by the same signal generator, that are a distance h (5m)
apart. You walk in the positive direction starting at y=0 m, along
a line parallel to the line joining the two speakers. The speed of
sound is 340 m/s and the frequency is 170 HZ. As you walk, how many
times and where will you hear a maximum sound?
