Question

Two waves overlap each other such that the combined amplitude is smallerthan the amplitude of either wave. This is a good example of...

Answer 1

The amplitudes of the waves are added or subtracted when two waves overlap or superpose.

if the amplitude of the resultant wave is greater, it is called the constructive interference.

if the resultant amplitude is less than the amplitudes of the superposing waves, it is the destructive interference.

Here, the answer is destructive interference.
