Two speakers are facing each other, 4.00 meters apart, in phase and playing a sound with frequency 170HZ. Find the distance from the center point to the nearest point where totally destructive interference occurs.

Expert Solution

For two sound waves travelling in opposite direction will lead to a combine wave called as standing wave. Standing wave have two interferences constructive and destructive. Destructive interference occurs at nodes and constructive interference occurs at antinodes. Nodes have zero amplitude while antinodes are having amplitude twice that of sound wave travelling alone.

Node position or destructive position is given as X (from the end).

Two speakers face each other, and they each emit a sound of wavelength (lambda). One speaker is 180 (degrees) out of phase with respect to the other. If we separate the speakers by a distance1.5 (lambda),how far from the left-most speaker should we place a microphone in order to pick up the loudest sound? Ignore reflections from nearby surfaces. Select all that apply. 3/4 lambda 0 lambda 1/2 lambda 1/4 lambda 1 lambda
