Two speakers are pointed towards a wall opposite them that is 5.00m away. The two speakers are positioned 3.5m apart from one another and emit a sound of single frequency (and are in phase). When an observer stands against the wall, midway between the two speakers, they hear constructive interference. If the observer moves 0.840m sideways (along the wall), they hear destructive interference. What is the path difference between d1 and d2? Continuing with the previous question, if the speed of sound is 343m/s, what must the lowest frequency of sound be that is emitted by the speakers?

Two loudspeakers, labeled A and B, emnit sound waves in every direction. Both speakers emit sound with the same wavelength, and they are in phase (they emit peaks of the sound wave at the same time). The location labeled C is a location of constructive interference, and the location labeled D is a location of destructive interference. The distances from the loudspeakers to the locations are as indicated. (Picture may not be to scale!!) (a) What is the wavelength of...

Two speakers, A and B, are 4.00 m apart and are emitting identical in-phase sound waves. The speed of sound in air is 340 m/s. Consider a line which is the perpendicular bisector of the line connecting the two speakers. The first interference maximum occurs at ±25.15 o from this line. (a) What is the frequency of the sound emitted? (b) Find the rest of the angles where constructive and destructive interference occur. (c) If the speakers are aboard a...

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...

This experiment requires two speakers that can be separated by some distance (try 1-2 meters). Try playing a single frequency using a tone generator and walk side to side in front of the speakers. Can you hear where there is constructive and destructive interference? Can you predict where the sound will get louder or quieter? What changes when you change the frequency?

In the figure, two loudspeakers, separated by a distance of d1 = 2.89 m, are in phase. Assume the amplitudes of the sound from the speakers are approximately the same at the position of a listener, who is d2 = 4.08 m directly in front of one of the speakers. Consider the audible range for normal hearing, 20 Hz to 20 kHz. (a) What is the lowest frequency that gives the minimum signal (destructive interference) at the listener's ear? (b)...

Two in-phase loudspeakers are placed along a wall and are separated by a distance of 4.00 m. They emit sound with a frequency of 514 Hz. A person is standing away from the wall, in front of one of the loudspeakers. What is the closest distance from the wall the person can stand and hear constructive interference? The speed of sound in air is 343 m/s. Multiple choice: 1.64 m 1.15 m 0.344 m 0.729 m
