Web1 apr. 2024 · Beats: When two sound waves of slightly different frequencies are sounded together, there occurs a periodic rise and fall of sound intensity. Such a phenomenon is known as beats. The time between a rise and a fall is called a beat period. The number of beats heard per second is called beat frequency. It is given by \(f_{}=f_2-f_1\) Web5 dec. 2024 · The beat frequency is defined as the difference in frequency between the two original waves.
