Is it necessary for production of beats that the two waves must have exactly equal amplitudes?

The cause of beats is that the two waves undergo

In the production of beats by two waves of same amplitude and nearly same frequency, the maximum intensity to each of the constituent waves is

Production Of Amplitude Modulated Wave

The amplitude factor of resulting wave, formed by superposition of two sinusoidal waves of equal amplitude a and constant phase difference is given by

Distinguish between conditions for the production of stationary waves and beats.

A particle is subjected to two simple hasrmonic motions in the same direction having equal amplitudes and equal frequency. If the resultant amplitude is equal to the amplitude of the individual motions, find the phase difference between the individual motions.

A particle is subjected to two simple harmonic motions in the same direction having equal amplitudes and equal frequency. If the resulting amplitude is equal to the amplitude of individual motions, the phase difference between them is
