About this Simulation

This interactive simulation models multiple slit diffraction and the superposition of waves. Learners can adjust slit configurations, wavelength, and observation distance to observe how waves from multiple slits interfere constructively and destructively, creating characteristic diffraction patterns with alternating bright and dark fringes.

Learning objectives: Understand how waves from multiple slits superpose to create interference patterns | Visualize the relationship between slit separation, wavelength, and fringe spacing | Explore how intensity varies across the diffraction pattern and connect it to constructive and destructive interference
