NEET Physics Huygens Principle Assertion Reason Question
Assertion (A): The amplitude of secondary wavelets is zero in the backward direction. | Reason (R): Huygens made an adhoc assumption to explain the absence of the backwave.
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
According to Huygens' Principle, the amplitude of secondary wavelets is maximum in the forward direction and zero in the backward direction. This was explained by Huygens through an adhoc assumption.
