NEET Physics Standing Waves Assertion Reason Question
Assertion (A): A standing wave pattern on a string with fixed ends shows nodes at the boundaries.
Reason (R): At a rigid boundary, the reflected wave undergoes a phase reversal.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
Standing waves on a string with fixed ends result in nodes at the boundaries due to phase reversal of the reflected wave at a rigid boundary, as described in the NCERT context.
