Answer:
Superposition of two wave crests produces destructive interference.
Explanation:
You may have already let your phone ring near the speakers of a computer and noticed that they started to sizzle. You must also have heard that, when traveling by plane, the cell phone must be turned off to avoid failures in the communication devices. Both cases have the same reason: wave interference. Waves are energetic pulses that propagate through space periodically. When two waves overlap in the same region of space, interference occurs, which results in another wave with different intensity. These inferences can be either constructive or destructive.
The superposition of two wave crests produces destructive interference. This type of inference occurs when two waves that meet have different phases, so that one annihilates the other. The result is a wave with zero amplitude.
