NEET Physics Wave Motion Assertion Reason Question
Assertion (A): Mechanical waves require a medium for their propagation. | Reason (R): Mechanical waves involve oscillations of constituent particles and depend on the elastic properties of the medium.
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.
Correct Answer
Detailed Explanation
The NCERT context states that mechanical waves require a medium for propagation and involve oscillations of particles, which depend on the medium's elastic properties. Therefore, R correctly explains A.
