Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 20 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 30 cm.

a. What is the wavelength of the sound?

b. If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?

Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 20 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 30 cm. a. What is the wavelength of the sound? b. If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?

In Example 18.1, we investigated an oscillator at 1.3 kHz driving two identical side-by-side speakers. We found that a listener at point O hears sound with maximum intensity, wheras a listener at point P hears a minimum. What is the intensity at P?

a) less than half dose to the intesity at O,
b) half the instensity at O,
c) very low but not zero,
d) zero or
e) indeterminate.
