NEET Physics Beats MCQ Question
Which of the following statements about beats is correct?
Beats occur when two waves of slightly different frequencies interfere.
The beat frequency is calculated as the sum of the two frequencies.
Beats can only be produced by waves of the same amplitude.
Increasing the frequency of one wave always increases the beat frequency.
Correct Answer
Detailed Explanation
Beats occur due to the interference of two waves with slightly different frequencies, which results in a modulation of amplitude at a frequency equal to the difference between the two frequencies, as indicated by the equation ν beat = ν 1 – ν 2.
