Physics-Huygens Principle
NEET Physics Huygens Principle MCQ Question
Type: MCQ-conceptual-Easy-Class 12
Which combinations accurately describe Huygens Principle?
A
A wavefront is a surface of constant phase, and each point on it acts as a source of secondary wavelets.
B
The speed of the wavefront is irrelevant to the direction of energy propagation.
C
Secondary wavelets propagate in all directions equally from each point on the wavefront.
D
The new wavefront can be determined by drawing tangents to the secondary wavelets from the original wavefront.
Correct Answer
Option A
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.
