NEET Physics Huygens Principle MCQ Question
What defines a wavefront according to Huygens Principle?
A surface of constant phase where all points oscillate in phase.
A line along which energy is transmitted in the backward direction.
A region where wave amplitudes are minimized.
A boundary between two different media where light speed changes.
Correct Answer
Detailed Explanation
According to Huygens Principle, a wavefront is defined as a surface of constant phase, where all points on the surface oscillate in phase due to being at the same distance from the source.
