NEET Physics Huygens Principle Assertion Reason Question
Assertion (A): Huygens' principle explains the absence of a backwave in wavefront propagation. | Reason (R): Huygens assumed that the amplitude of the secondary wavelets is maximum in the forward direction and zero in the backward direction.
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 but R is true.
Correct Answer
Detailed Explanation
Huygens' principle includes the assumption that the amplitude of secondary wavelets is maximum in the forward direction and zero in the backward direction, explaining the absence of a backwave.
