2. A 1,720-Hz pure tone is played on a stereo in an open field. A person stands at a point that is 8 m from one of the speakers and 8.7 m from the other. Does the person hear the tone? (Assume the speed of sound is 344 m/s.) The path difference of _____ is ______ times the wavelength of the tone, giving _________ interference.

A person stands directly in front of two speakers that are emitting the same pure tone. The person then moves to one side until no sound is heard. At that point, the person is 8.15 m from one of the speakers and 8.19 m from the other. What is the frequency (in Hz) of the tone being emitted? (Assume air temperature to be 20°C.)

A stereo speaker produces a pure "E" tone, with a frequency of 329.6 Hz. What is the period of the sound wave produced by the speaker? period: What is the wavelength of the same sound wave as it enters some water, where it has a speed of about 1480 m/s? wavelength entering water: What is the wavelength of this sound wave as it travels through air with a speed of about 341 m/s? wavelength in air

Two speaker emit the same pure tone at 170 Hz, but they are half a cycle out of phase with each other (so one produces a "trough" exactly when the other one produces a "crest"). The speakers are three meters apart. You are standing between the speakers, one meter from one (and therefore two meters from the other). What do you hear? The speed of sound in air is 340 m/s. O A 170 Hz tone, but very quietly, if...

Paisley stands in front of two speakers as shown which emit the same tone, in phase. She is 7.00 m from speaker A and 5.00 m fromB speaker B. a. What are the two lowest frequencies for which she hears: i. a loud sound? [171.5 Hz, 343 Hz] ii. a quiet sound [85.8 Hz, 257 Hz] d-5.00m A-7.00m b. The frequency of the speakers is then changed to 686 Hz Does Paisley hear a loud sound or a quiet sound?...

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...

You are driving south on a road at a speed of 21.3 m/s and you hear a siren from a police car at a frequency of 915 Hz, as the police car approaches you while driving north. If the police car is going at a speed of 32.4 m/s, and the speed of sound is 343 m/s, what frequency would...

You are walking around a large open field. The only objects nearby are two identical speakers set some distance apart, which are both producing sound in unison, with a wavelength of 4 m. As you wander around the field, you notice that at certain locations the sound you hear is surprisingly loud, whereas at others it seems unusually quiet. You conclude that you are observing the effects of interference between the two sources of sound waves. For each of the...

1. (10 points) Two identical speakers are continuously emitting sound waves uniformly in all directions at 440 Hz. The speed of sound is 344 m/s. Point P is a distance of r = 3.13 m away from speaker 1 and r2 = 4.30m from speaker 2: i. What is the phase difference between the waves at Point P? ii. Is this a point of constructive interference, destructive interference, or something in between? Explain.
