MHT CET · Physics · Waves and Sound
For formation of beats, two sound notes must have
- A Different amplitudes and different frequencies
- B Exactly equal frequencies only
- C Exactly equal amplitudes only
- D Nearly equal frequencies and equal amplitudes
Answer & Solution
Correct Answer
(D) Nearly equal frequencies and equal amplitudes
Step-by-step Solution
Detailed explanation
In a sound notes various frequencies are mixed, hence beats can produced by two sound notes only when they have nearly equal frequencies and equal amplitudes.
