What is meant by beats and beat frequency?

Beats are caused by the interference of two waves at the same point in space . This plot of the variation of resultant amplitude with time shows the periodic increase and decrease for two sine waves.

Beat is produced when two waves of nearby frequencies superimpose when they travel in the same path . This causes a periodic variation of intensity of the resultant wave. The beat frequency is the number of beats produced per second.

The beat frequency is equal to the complete value of the alteration in the frequency of the two waves. The count of beats per second is equivalent to the difference in frequencies of two waves is called beat frequency. … Beat Frequency Formula: fbBeat frequencyf1Frequency of 1st wavef2Frequency of 2nd waveBeat Frequency Formula – Toppr www.toppr.com › guides › physics-formulas › beat-frequency-formula
