NEET Physics Standing Waves MCQ Question
Which of the following statements about standing waves are correct?
Standing waves are produced by the interference of two identical waves moving in opposite directions.
At a rigid boundary, the reflected wave has the same phase as the incident wave.
At an open boundary, the reflected wave undergoes a phase change of π.
The maximum displacement at a non-rigid boundary is equal to the amplitude of the incident wave.
Correct Answer
Detailed Explanation
Statement A is correct as it describes the formation of standing waves. Statement B is incorrect because the reflected wave at a rigid boundary undergoes a phase reversal. Statement C is incorrect as an open boundary does not involve a phase change. Statement D is incorrect since the maximum displacement at a non-rigid boundary is twice the amplitude of the incident wave.
