NEET Physics Standing Waves MCQ Question
Consider a string tied to a freely moving ring on a rod, with a wave traveling along it. If the wave is reflected at the open boundary, how does the phase of the reflected wave compare to the incident wave?
The phase of the reflected wave remains unchanged.
The phase of the reflected wave changes by π.
The phase of the reflected wave changes by 2π.
The phase of the reflected wave changes by 3π.
Correct Answer
Detailed Explanation
At an open boundary, a wave is reflected without any phase change, meaning the phase of the reflected wave remains the same as the incident wave.
