Two-Source Wave Interference

About This MicroSim

This simulation demonstrates wave interference from two coherent sources. When waves from both sources overlap, they create an interference pattern with regions of constructive interference (bright/high amplitude) and destructive interference (dark/low amplitude).

Key Concepts

  • Constructive Interference: Waves in phase combine to larger amplitude
  • Destructive Interference: Waves out of phase cancel each other
  • Nodal Lines: Lines of permanent destructive interference
  • Antinodal Lines: Lines of permanent constructive interference
