NEET Physics Transverse & Longitudinal Waves Assertion Reason Question
Assertion (A): In a stationary wave on a string, the distance between two successive nodes is equal to half the wavelength.
Reason (R): The positions of nodes are determined by the condition that the amplitude of vibration is zero at these points.
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
In a stationary wave, nodes are points where the amplitude is zero, occurring at intervals of λ/2. Thus, the reason correctly explains the assertion.
