Wave Interference

Simulate electromagnetic wave interference patterns from two coherent light sources. Observe constructive and destructive interference. (like Young's double-slit experiment!)

Physics Explanation

Constructive Interference: When waves are in phase (phase difference = 0°, 360°, etc.), they add together to create a larger amplitude.

Destructive Interference: When waves are 180° out of phase, they cancel each other out (dark regions).

The interference pattern depends on path difference: Δx = nλ (constructive) or Δx = (n+½)λ (destructive).
