Question
Two waves meet and the trough of one matches with the crest of another. The result is a standing wave. What type of interaction is this?AconstructiveBdestructiveCfreqencyDresonance
Solution
The interaction described is a type of wave interference known as destructive interference. So, the answer is Bdestructive.
Here's why: When two waves meet and the trough (lowest point) of one wave aligns with the crest (highest point) of another wave, they cancel each other out. This is because the positive displacement of one wave (the crest) is cancelled by the negative displacement of the other wave (the trough). This results in a point of no displacement, or a node, which is a characteristic of a standing wave. This type of interaction is known as destructive interference.
