NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 11
Assertion (A): At a node in a standing wave, pressure changes are at a maximum. | Reason (R): In a standing wave, the antinode experiences the least pressure change and maximum displacement.
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.
Correct Answer
Option A
Detailed Explanation
At a node, pressure changes are indeed at a maximum, as detailed in Chunk 3. This occurs because displacement is minimum, leading to maximum pressure variation, while the antinode has maximum displacement and least pressure change.
