two sound waves are slightly different frequencies propagating in the same direction overlap each other and produce waxing and wanning of sound at regular intervals of time.

When two waves of slightly different frequencies propagating in same direction results in the formation of waxing and waning sounds due to interference of waves.& this phenomenon is called beats

hellow kumar In acoustics, a beat is an interference between two sounds of slightly different frequencies, perceived as periodic variations in volume whose rate is the difference between the two frequencies.

DEAR KUMAR BEAT FREQUNCE MEANS TWO SOUND WAVES SLIGHTLY DIFFERENCE FREQUENCIES ARE PROPAGATING IN A SAME DIRECTION TWO ARE OVERLAP EACH OTHER TO PRODUCE WAXING WANNING SOUNDS AT REGULAR INTERVALS OF TIME

BEAT FREQUENCY MEANS TWO SOUND WAVES SLIGHTLY DIFFERENT FREQUENCYES PROPRGATING IN A MEDIUM IN THE SAME DIRECTION TO PRODUCE WAXING AND WANNING OF SOUND AT REGULAR INTERVALS.EUATION FOR BEAT FREQUENCY IS Fa-Fb=F.

dear kumar Beats are often observed between two vibrations with similar frequencies. The beat frequency equals the difference between frequencies of the beating signals.
