Beats
BEATSIf two tuning fork whose frequency is slightly different are sounded together , the sound we hear periodically fluctuates in intensity , i.e intensity increases and decreases suddenly . This periodic variations in intensity of sound are called beats. So we can define “ Beats are periodic vibration in the intensity of sound when two […]
