Huygens Interference
Interactive lab: Place sources and watch wavefronts, diffraction, and interference emerge.
What is this?
A visual, interactive experiment about Huygens Interference. Its main parameters update live and the simulation runs entirely in the browser.
How it works
Every point acts as a secondary source. Amplitude superposition creates wavefronts and far-field fringes spaced by Δy ≈ λL/d.
