Interference is an effect that occurs when two or more waves
overlap.

Approved

In physics, interference is a phenomenon in which two waves superimpose to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, and surface water waves.

1)Super position of two or more waves is called interference.

2)Itnrerference is also called as combination of two or more choherence waves.
