What type of wavefront will emerge from a (i) distant light source and (ii) point source?
- A (i) Spherical; (ii) Plane
- B (i) Plane ; (ii) Spherical
- C (i) Spherical ; (ii) Spherical
- D (i) plane; (ii) Plane
Answer & Solution
Correct Answer
(B) (i) Plane ; (ii) Spherical
Step-by-step Solution
Detailed explanation
A point source emits light in all directions, creating a spherical wavefront. However, as these waves travel a very large distance from a distant source, the curvature becomes negligible, and a small portion of the wavefront appears as a plane wavefront. B) (i) Plane ; (ii)…
