When the crest of one wave overlaps the trough of another, this produces destructive interference. If both original waves are equal in amplitude, then nothing will remain. The waves completely cancel out. However, if one waver is larger in amplitude, then there will still be a wave left over after they meet, but it will be smaller. The amplitude of the new wave will be the larger wave amplitude minus the smaller wave amplitude one. The opposite can also occur. If the crests of two waves overlap, then it produces constructive interference (resulting in one larger wave).
When two or more waves overlap, it is called interference. Interference can result in amplification (constructive interference) or cancelation (destructive interference) of the waves depending on their phase relationship.
When two waves meet and overlap, it is called interference. Interference can result in constructive interference, where the amplitude of the resulting wave is increased, or destructive interference, where the amplitudes partially or completely cancel each other out.
When two or more waves overlap each other, it is called interference. Interference can result in either constructive interference, where the amplitude of the resulting wave is increased, or destructive interference, where the amplitude is decreased.
The principle is superposition. This means that when two waves overlap, their displacements add up to create a new wave that is the sum of the two individual waves.
When the crest of two waves overlap and result in an increased wave amplitude, it is called constructive interference. This phenomenon occurs when the peaks of two waves align, reinforcing each other to create a larger wave.
