प्रश्न
Describe the formation of beats.
उत्तर
When two or more waves superimpose each other with slightly different frequencies, then a sound having periodically varying amplitude at a point is observed. This phenomenon is known as beats. The number of amplitude maxima per second is called beat frequency. If we have two sources, then their difference in frequency gives the beat frequency.
Number-of beats per second
n = `|"f"_1 - "f"_2|` per second
