NEET Physics Huygens Principle MCQ Question
Which of the following statements about Huygens Principle is correct?
A wavefront is defined as a surface of constant phase, where all points oscillate in phase.
The speed of the wavefront is independent of the medium through which the wave travels.
Huygens Principle states that only the points on the wavefront contribute to the formation of the next wavefront.
Secondary wavelets from a wavefront have maximum amplitude in the backward direction.
Correct Answer
Detailed Explanation
Statement A correctly defines a wavefront as a surface of constant phase where all points oscillate in phase. The other options misrepresent key aspects of Huygens Principle, such as the behavior of wavefronts and secondary wavelets.
