NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): In a longitudinal wave, the particles of the medium oscillate parallel to the direction of wave propagation. | Reason (R): The boundary conditions at a rigid wall result in a phase change of π for reflected waves.
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 B
Detailed Explanation
While both statements are true, the reason provided does not explain the assertion. The assertion is about particle motion in a longitudinal wave, while the reason discusses phase change upon reflection at a rigid boundary.
