6-1 Two speakers emit sound waves with frequency 4.27 kHz s pts by the same oscillator so that they are in phase with each other. I place the They are driven speakers side-by-side, and I stand across the room from them. If someone moves one of the speakers towards me, I hear the total intensity drop and then rise again. How far had they moved the speaker at the point whereI heard a minimum intensity due to destructive interference of...
Two identical loudspeakers separated by distance d emit 200 Hz sound waves along the x-axis. As you walk along the axis, away from the speakers, you don't hear anything even though both speakers are on. What are the three lowest possible values for d? Assume a sound speed of 340 m/s . The answer I get is 0.875, 2.625, 4.375 and mastering physics says its wrong
Two identical loudspeakers 2.10 m apart are emitting sound waves into a room where the speed of sound is 340 m/s. Abby is standing 5.00 m in front of one of the speakers, perpendicular to the line joining the speakers, and hears a maximum in the intensity of the sound. What is the lowest possible frequency of sound for which this is possible?
Two radio antennas are separated by 2.00 m . Both broadcast identical 750 MHz waves. If you walk around the antennas in a circle of radius 20.0 m , how many maxima will you detect?
Two identical loudspeakers separated by distance demit 170 Hz sound waves along the x-axis. As you walk along the axis, away from the speakers, you don't hear anything even though both speakers are on. What are the three lowest possible values for d? Assume a sound speed of 340 m/s .
Two in-phase loudspeakers are placed along a wall and are separated by a distance of 6.00 m. They emit sound (take vs = 343 m/s) with a frequency of 137.2 Hz. A person is standing away from the wall, in front of one of the loudspeakers. What is the closest distance x from the speaker the person can stand and hear a sound intensity maximum? 4. [5] Two in-phase loudspeakers are placed along a wall and are separated by a...
Two stereo speakers mounted 5.2 m apart on a wall emit identical in -phase sound waves. You are standing at the opposite wall of the room at a point directly between the two speakers. You walk 2.11 m parallel to the wall, to a location where you first notice that the sound intensity drops to zero. If the wall along which you are walking is 10.7 m from the wall with the speakers, what is the wavelength of the sound...
Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 22cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 50cm . If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?
Interference with Loudspeakers Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves OUT of phase. The frequency of the waves emitted by each speaker is 172 Hz. You are 8.00 m from speaker A. Take the speed of sound in air to be 344 m/s.(Hint: out of phase means their phase constants differ by pi ) (a) What is the closest you can be to speaker B and be at a point of maximum...
Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 42 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 49 cm . What is the wavelength of the sound? If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?
