What is the difference between interference and beats?
Asked by Topperlearning User | 04 Jun, 2014, 01:23: PM
answered-by-expert Expert Answer

Interference pattern is produced when two waves of same frequency travelling in same direction superimpose, while beats are formed when frequencies are slightly different.

In interference, the position of maximum and minimum are permanent i.e., intensity at a given point does not change with time, but in beats the intensity of wave changes at given point with time.
