NCERT · Class 12 · Physics · Wave OpticsWhich shape of wavefront is obtained from a point source of light at a finite distance?
Step-by-Step Solution
The correct answer is Spherical. A point source emitting light in all homogeneous directions produces a spherical wavefront because all points equidistant from the source vibrate in the same phase.
