Constructive Interference

The interference of two or more waves of equal frequency and phase, resulting in their mutual reinforcement and producing a single amplitude equal to the sum of the amplitudes of the individual waves.

Destructive Interference

Standing Wave

The wave doesn’t propagate. It just sits there vibrating up and down in place.

Pulse Wave

A kind of non-sinusoidal waveform that is similar to a square wave, but does not have the symmetrical shape associated with a perfect square wave.

Periodic Wave

A series of regularly timed disturbances in a medium.

Transverse Wave

A wave vibrating at right angles to the direction of its propagation.

Longitudinal Wave

A wave vibrating in the direction of propagation.
