Answer 1

Answer #1

Highest intensity = 15cm
Lowest intensity = 62cm

that is 62-15 = 47 = $\lambda$ / 2

$\lambda$ = 47*2 = 94 cm ..................answer

From 62 cm to another point of high intensity = 62 + 47 = 109 cm

Along one axis, the two groups cheer the loudest when they are 14 m apart. The cheering intensity decreases (due to interference) as the distance between the two groups is increased, reaching zero when the two groups are 57 m apart. a) What is the wavelength of the sound? (include units) b) If the distance between the speakers increased further, at what separation distance will the cheering intensity again be at a maximum? include units)

Two loudspeakers, 1.3 m apart, emit sound waves with the same frequency along the positive x-axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency? Assume room temperature of 20∘C.

Two loudspeakers, labeled A and B, emnit sound waves in every direction. Both speakers emit sound with the same wavelength, and they are in phase (they emit peaks of the sound wave at the same time). The location labeled C is a location of constructive interference, and the location labeled D is a location of destructive interference. The distances from the loudspeakers to the locations are as indicated. (Picture may not be to scale!!) (a) What is the wavelength of...

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...
