NEET Physics Wave Motion Assertion Reason Question
Assertion (A): The interference of two identical waves moving in opposite directions produces standing waves. | Reason (R): For a string with fixed ends, the standing wave is given by y(x, t) = [2a sin kx] cos ωt.
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
Both the assertion and the reason are correct. The interference of two identical waves moving in opposite directions results in standing waves, and the given equation describes the standing wave pattern for a string with fixed ends.
