NEET Physics Huygens Principle MCQ Question
Which of the following statements about Huygens' Principle is correct?
Huygens' Principle states that every point on a wavefront acts as a new source of secondary wavelets.
The amplitude of secondary wavelets is maximum in the backward direction.
Huygens' Principle can only be applied to light waves in a vacuum.
Secondary wavelets do not contribute to the formation of a new wavefront.
Correct Answer
Detailed Explanation
Huygens' Principle asserts that every point on a wavefront serves as a source of secondary wavelets, which combine to form the new wavefront. This principle does not support the idea of maximum amplitude in the backward direction or limit its application to a vacuum.
