A) Frequency different, amplitude same
B) Frequency same, amplitude same
C) Frequency same, amplitude different
D) None of the above
Correct Answer: A
Solution :
When two sound waves of slightly different frequencies, travelling in a medium along the same direction, superimpose on each other, the intensity of the resultant sound at a particular position rises and falls alternately with time. This phenomenon of alternate variation in the intensity of sound with time at a particular position, when two sound waves of nearly equal frequencies and same amplitude superimpose on each other is called beats.
