Physics-Huygens Principle
NEET Physics Huygens Principle MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a diagram where spheres of radius vt are drawn from each point on a spherical wavefront, and a common tangent is drawn to all these spheres. What does this tangent represent?
A
The new position of the wavefront
B
The path of light rays
C
The backwave in the wave model
D
The reflected wavefront
Correct Answer
Option A
Detailed Explanation
The tangent drawn to all spheres represents the new wavefront position, as each point on the tangent is equidistant from the origin of the wavefront. This aligns with Huygens' principle of constructing wavefronts.
