Huygens' Principle
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Every point on a wavefront can be considered as a new source emitting spherical wavelets. The envelope of these wavelets forms the new wavefront.
SCAFFOLDING EFFECT
Reduce cognitive load
Fission propagation. Do not view propagation as a single process radiating outward from a center. Instead, treat every person (node) affected as a new 'center' (source). Design mechanisms so that the audience becomes new sources of propagation, not just receivers.
Anchor fast decisions
Every point on a wavefront can be regarded as a source emitting secondary spherical wavelets. The wavefront at the next moment is the envelope of these wavelets; this can uniformly explain reflection, refraction, and diffraction of waves.
