NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 12
Consider a diagram showing the refraction of a plane wave by a convex lens. If the focal point is indicated on the diagram, what is true about the behavior of wavefronts as they pass through the lens?
A
Wavefronts converge towards the focal point.
B
Wavefronts diverge away from the focal point.
C
Wavefronts remain parallel after passing through the lens.
D
Wavefronts reflect back from the lens surface.
Correct Answer
Option A
Detailed Explanation
In a convex lens, wavefronts converge towards the focal point after passing through the lens as described in the NCERT context, which explains the behavior of wavefronts during refraction.
