A wave interference where rhe wave amplitudes combine to yield a lesser amplitude than either of the waves is known as a
A) standing wave
B) constructive interference
C) destructive interference
D) transverse wave
The correct answer is C) destructive interference.
To understand why, let's first quickly explain what interference is. Interference occurs when two or more waves meet each other at the same point in space and time. When this happens, the waves interact with each other, resulting in a modification of their amplitudes (the measure of their intensity or strength).
In the case of constructive interference, the amplitudes of the two waves add together, resulting in a larger combined amplitude. This happens when the peaks of one wave align with the peaks of another wave, or when the troughs align with the troughs.
On the other hand, destructive interference occurs when the amplitudes of the two waves subtract from each other, resulting in a smaller combined amplitude. This happens when the peak of one wave aligns with the trough of another wave.
So, when waves interfere in such a way that their amplitudes combine to yield a lesser amplitude than either of the waves individually, it is known as destructive interference.
