NEET Physics Standing Waves Assertion Reason Question
Assertion (A): In a standing wave formed on a string with fixed ends, nodes are points of zero displacement. | Reason (R): The interference of two identical waves moving in opposite directions produces standing waves.
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 and R is true.
Correct Answer
Detailed Explanation
In the NCERT context, standing waves are described as resulting from the interference of two identical waves moving in opposite directions, leading to nodes, which are points of zero displacement at fixed ends.
