PRACTICE TEST PAPER CHAPTER 15: PHYSICAL OPTICS Answer Key & Detailed Solutions VERSION 1 — DETAILED SOLUTIONS Q.1 — MCQs (Version 1) (c) Wavefront Explanation: By definition, a wavefront is an imaginary surface that connects all adjacent points of a wave that share the exact same phase of oscillation. (b) Spherical Explanation: A point source in three-dimensional space emits waves uniformly in all directions. The locus of points at equal distance/phase forms concentric spheres. (d) Explanati…
