interference

In interference
The resultant effect is a complex wave. A pulsating frequency, called a beat, results when the wavelengths are slightly different. Figures D, E, and F show complex waves (solid lines) composed of two component interfering waves (dotted lines), the ratio of their wavelengths being 1:2 and of their amplitudes 1:3.
