32. Two loudspeakers, A and B , are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m to the right of speaker A. Consider point Q along the extension of the line connecting the speakers, 1.00 m to the right of speaker B. Both speak- ers emit sound waves that travel directly from the speaker to point Q. (see figure) (a) What is the lowest frequency for which constructive interference occurs at point...

Two in-phase loudspeakers, which emit sound in all directions, are sitting side by side. One of them is moved sideways by 6.0 m, then forward by 6.0 m. Afterward, constructive interference is observed 1/4 and 3/4 of the distance between the speakers along the line that joins them. Part A What is the maximum possible wavelength of the sound waves?
Two in-phase loudspeakers, which emit sound in all directions, are sitting side by side.
Two in-phase loudspeakers, which emit sound in all directions, are sitting side by side. One of them is moved sideways by 2.0 m, then forward by 8.0 m. Afterward, constructive interference is observed 1/4 1/2, and 3/4 the distance between the speakers along the line that joins them, and at no other positions along this line. What is the maximum possible wavelength of the sound waves?

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?

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 17 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 70 cm . What is the wavelength of the sound? (Express your answer to two significant figures and include the appropriate units.) (btw its not 106 cm)
