NEET Physics Huygens Principle MCQ Question
Which combinations accurately describe Huygens Principle?
A wavefront is a surface of constant phase, and each point on it acts as a source of secondary wavelets.
The speed of the wavefront is irrelevant to the direction of energy propagation.
Secondary wavelets propagate in all directions equally from each point on the wavefront.
The new wavefront can be determined by drawing tangents to the secondary wavelets from the original wavefront.
Correct Answer
Detailed Explanation
According to Huygens Principle, a wavefront is defined as a surface of constant phase, and each point on it indeed acts as a source of secondary wavelets. The energy of the wave travels in a direction perpendicular to the wavefront, which is not captured by options B and C.
