NEET Physics Standing Waves Assertion Reason Question
Assertion (A): A standing wave is formed on a string with fixed ends when two identical waves move in opposite directions. | Reason (R): The reflection of a wave at a rigid boundary involves 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.
Correct Answer
Detailed Explanation
A is true because standing waves are formed by interference of two identical waves moving in opposite directions. R is true, but it explains the behavior of wave reflection at rigid boundaries, not specifically the formation of standing waves.
