Final answer:
Destructive interference occurs when two waves cancel each other out, resulting in a decrease or elimination of amplitude. To set up a demonstration of destructive interference, place two speakers facing each other and adjust the phase of one speaker. The layout of the space and distance between the speakers should be considered.
Step-by-step explanation:
Destructive interference occurs when two waves combine to cancel each other out, resulting in a decrease or complete elimination of amplitude. In the case of sound waves, two speakers can exhibit destructive interference when the waves they produce are out of phase.
To set up a demonstration of destructive interference, the student can place two speakers facing each other, equidistant from a point in space. The speakers should be emitting the same frequency of steady tone. By adjusting the phase of one of the speakers, the student can create areas where the waves cancel each other out, resulting in points of low or zero sound intensity.
It's important to note that the layout of the space and the distance between the speakers will affect the interference pattern. The student should ensure that the speakers are at an appropriate distance from each other and from the point where they want to observe destructive interference.
