The wavefronts from a point source are:

ASpherical

BFlattened

CConical

DStraight

Answer & Solution

Correct answer: A. Spherical

1. The source sends waves out equally in every direction. 2. Points of equal phase then lie at equal distances from it. 3. So the wavefronts are spheres. _Source: syllabus Physics Part II, Chapter 10, Wave Optics._
