alleryA point source sends waves out evenly in all directions. Its wavefronts are:
AFlat planes
BCylindrical
CCube shaped
DSpherical
Answer & Solution
Correct answer: D. Spherical
1. Points at one distance from the source are in phase.
2. Those points form a sphere around the source.
3. So the wavefronts are spherical.
