NEET Physics Wave Motion Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

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.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false but R is true.

Correct Answer

Option A

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.
