**Huygens' principle** states that every point on a wavefront acts as a:

  1. Source of plane waves only
  2. Secondary source emitting wavelets in all directions
  3. Absorber of waves
  4. Source of longitudinal waves only
Show answer and solution

Correct answer: B. Secondary source emitting wavelets in all directions

Each point on a wavefront becomes a secondary source of spherical wavelets. The new wavefront at a later time is the **envelope** of these wavelets in the forward direction (backward wavelets are taken as ineffective).
