NEET Physics Standing Waves MCQ Question
Which of the following statements about standing waves and their formation is correct?
Standing waves are formed by the superposition of two waves traveling in opposite directions with the same frequency.
Standing waves can only exist in open boundaries where there is no phase change upon reflection.
At a rigid boundary, the reflected wave has the same phase as the incident wave, leading to constructive interference.
Standing waves cannot form if the waves are not identical in amplitude and frequency.
Correct Answer
Detailed Explanation
Standing waves are created through the interference of two identical waves moving in opposite directions, as stated in the NCERT context. This phenomenon relies on the principle of superposition and requires the waves to have the same frequency and amplitude for effective cancellation and reinforcement.
