NEET Physics Wave Motion MCQ Question
Which of the following statements about wave motion and superposition is correct?
The speed of a wave depends solely on its frequency.
When two waves interfere, the resulting wave's amplitude can be less than the amplitude of the individual waves.
In a longitudinal wave, the displacement of the medium is perpendicular to the direction of wave propagation.
The principle of superposition states that two waves cannot interact with each other.
Correct Answer
Detailed Explanation
According to the principle of superposition, when two waves interfere, they can create a resultant wave whose amplitude can be less than the individual waves, especially in cases of destructive interference. This is illustrated in the context of wave motion where amplitude variations occur due to interference effects.
