NEET Physics Wave Motion Assertion Reason Question
Assertion (A): A wave described by the equation y = 2a sin kx cos ωt does not represent a traveling wave.
Reason (R): In this wave pattern, the terms kx and ωt appear separately and the amplitude varies from point-to-point.
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
The given equation represents a standing wave, not a traveling wave, because kx and ωt appear separately, leading to point-to-point amplitude variation, as described in the NCERT context.
