For production of beats different frequencies are essential. The different amplitudes affect the minimum and maximum amplitude of the beats and different phases affect the time of occurrence of minimum and maximum.

1. True
2. False
3. Cannot be determined
4. Depends on the medium

Correct answer: True

Solution

The statement is true because beats are produced due to the interference of two sound waves of slightly different frequencies, and the amplitude and phase differences influence the resultant amplitude and timing of the beats.
