NEET Physics Wave Motion MCQ Question
Which of the following statements about wave motion and superposition is correct?
The amplitude of the resultant wave in superposition is the sum of individual amplitudes when waves are in phase.
Two waves of different frequencies can interfere constructively regardless of their phase difference.
The principle of superposition states that the displacement of the medium is the product of individual displacements.
The resultant waveform from two overlapping waves is independent of their phase relationship.
Correct Answer
Detailed Explanation
When two waves are in phase, their amplitudes add up, leading to a greater resultant amplitude. This is a direct application of the principle of superposition as described in the context of harmonic travelling waves.
