Question

Discuss the formation of beats analytically and hence calculate the beat frequency

Answer 1

Explanation:

When two waves are observed at a point in space, they are periodically in and out of phase. That is, there is a temporal (time) alternation between constructive and destructive interference. As a consequence, we refer to this phenomenon as temporal interference.

For example, if two tuning forks of slightly different frequencies are struck, one heara a sound periodically varying amplitide. This phenomenon is called beating.

Beating is the periodic variation in amplitude at a given point due to the superposition of two waves having slightly different frequencies.

The waves produced are called Beats.

The number of amplitude maxima one hears per second, or the beat frequency, equals the difference in frequency between the two sources.

$\boxed{\boxed{\sf{f_{beat}=|f_1-f_2|}}}$

Answer 2

Answer:

Beating is the periodic variation in amplitude at a given point due to the superposition of two waves having slightly different frequencies. The waves produced are called Beats. The number of amplitude maxima one hears per second, or the beat frequency, equals the difference in frequency between the two sources.
