Interference
When two or more waves overlap each other
noise cancelling
Interference does not occur when one wave is brighter than another, and the fainter wave cannot be observed. It occurs when two or more waves overlap.
Superimposing of waves is when two or more waves travel through the same medium and intersect. The net displacement is the addition of the waves amplitude. If they are in phase they increase amplitude; out of phase, the amplitude decreases.
Wave amplification
Resonance.

the amplitudes add together
The resultant wave has double the amplification
"lower amplitude"
