What is the shape of a wavefront when light emerging out of a convex lens when a parallel beam of light incident over it ?
- A Parabolic
- B Plane
- C Cylindrical
- D Spherical
Answer & Solution
Correct Answer
(D) Spherical
Step-by-step Solution
Detailed explanation
When a parallel beam (plane wavefront) passes through a convex lens, it converges toward the principal focus. Light that converges to or diverges from a point always forms a spherical wavefront. D) Spherical
