Question:
The type of wavefront that emerges from a distant light source is:
The type of wavefront that emerges from a distant light source is:
Show Hint
When light travels from a distant source, the wavefronts can be approximated as plane waves due to the parallel nature of the rays.
Updated On: Apr 23, 2025
- Cylindrical
- Plane
- Diverging spherical
- Converging spherical
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
A distant light source produces approximately plane wavefronts because the rays coming from the source are nearly parallel. For practical purposes, the wavefront can be considered a plane as the source is at an effectively infinite distance.
