A speaker plays a single musical note into the apparatus shown below. The sound takes two paths to an opening where a receiver is positioned. One path is fixed in length, while the other can be adjusted. Suppose that the receiver detects constructive interference at a particular instant. The speaker is producing sound with a frequency of 652 Hz, and that sound travels through the tubes at 343 m/s. By what minimum amount (in cm) should the adjustable path length be increased for the receiver to detect destructive interference?

Two loudspeakers, placed with respect to an observation point P as shown in the diagram below, emit identical pure tones of f = 343 Hz. The speed of sound in air is 343 m/s. The minimum speaker separation s for experiencing complete destructive interference at P is s = m.
Two loudspeakers are placed above and below each other, as in the figure, and driven by the same spice at a frequency of 5.60* 10^2 Hz. An observer is in front of the speakers at point O, at the same distance from each speaker. What max vertical distance upward should the top speaker be moved to create destructive interference at point O? ( assume spread of sound is 343m/s)
. Two loudspeakers A and B are driven by the same amplifier and emit pure sinusoidal waves in phase. (a) For what frequencies does constructive interference occur at point P? (b) For what frequencies does destructive interference occur at point P? The speed of sound is 350 m/s.
Two loudspeakers are placed above and below each other, as in the figure below, and driven by the same source at a frequency of 4.40 ✕ 102 Hz. An observer is in front of the speakers (to the right) at point O, at the same distance from each speaker. What minimum vertical distance upward should the top speaker be moved to create destructive interference at point O? (Let h = 2.58 m and use v = 343 m/s.)
Two stereo speakers are each emitting a pure tone of 200 Hz, and the waves have the same phase as they leave each speaker. The speed of sound in the room is 330 m/s. You are standing between the speakers, 1.65m from one speaker and 4.95 from the other. What type of interference do you perceive? (first, calculate the wavelength of sound, then work out the distances to each speaker as a number of wavelengths) Answer choices, pick one: a) destructive b) partial c)none d) constructive
Two speakers, speakers 1 and 2, located 0.750 m apart from each other, are creating sound waves with an identical frequency of 686 Hz and are in phase. Assume the speed of sound in the room is 343 m/s. Your ear is directly in line with the speakers. a) Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location? b) You now go and stand directly in between the two speakers (0.375 m to the right of speaker 1 and 0.375 m to the left of speaker 2). Do you hear a sound with maximum intensity, a sound with minimum intensity (ideally no intensity), or something in between at your location?
Point P is adistance of 8.5 m and 9.5 m from a speaker set. Both speakers emit identical sound waves with a wavelength of 1.0 m.a) If the waves are being emitted from both speakersin-phase, what kind of interference occurs at point P?b) What if the speakers emit waves out of phase by πradians? What interference would occur at P?
A riverside warehouse has several small doors facing the river. Two of these doors are open as shown in Figure P27.17. The walls of the warehouse are lined with sound-absorbing material. Two people stand at a distance L = 150 in from the wall with the open doors. Person A stands along a line passing through the midpoint between the open doors, and person B stands a distance y = 20 m to his side. A boat o the river sounds its horn. To person A, the sound is loud and clear. To person B, the sound is barely audible. The principal wavelength of the sound waves is 5.00 m. Assuming person B is at the position of the first minimum, determine the distance d between the doors, center to center.
In a two-point source interference pattern in a ripple tank, a point is one wavelength farther from one sourcethan the other. If the two sources are in phase, then there isa. destructive interference at this pointb. constructive interference at this pointc. both constructive and destructive interference simultaneouslyd. neither constructive nor destructive interference at this pointe. no interaction between the two waves at this point
Imagine you are in an open field where two loudspeakers are set up and connected to the same amplifier so that they emit sound waves in phase at 688 HzHz. Take the speed of sound in air to be 344 m/sm/s. What is the shortest distance d you need to walk forward to be at a point where you cannot hear the speakers? The forward direction is defined as being perpendicular to a line joining the two speakers and you start walking from the line that joins the two speakers.
The analysis of any two-point source interference pattern and a successful determination of wavelength demands an ability to sort through the measured information and equating the values with the symbols in Young's equation. Apply your understanding by interpreting the following statements and identifying the values of y, d, m and L. Finally, perform some conversions of the given information such that all information share the same unit. The fifth antinodal line and the second nodal line on the opposite side of an interference pattern are separated by a distance of 32.1 cm when the slits are 6.5 m from the screen. The slits are separated by 25.0 micrometers. y= ________ d=________ m=_______ L=________
Wave X has amplitude A and wavelength ?. Its angular frequency is 3? rad/s, and it is traveling southwards. Wave Y also has amplitude A and wavelength ?, and is also traveling southwards. Its angular frequency is 5? rad/s. At time zero, the interference of X and Y is perfectly constructive. When will they next interfere this way?
