About this Simulation

This simulation models multiple slit diffraction and wave superposition phenomena. Learners can adjust slit configurations, wavelength, and viewing range to observe how waves interfere constructively and destructively, creating characteristic diffraction patterns on a screen.

Learning objectives: Understand how multiple slits create interference patterns through wave superposition | Explore the relationship between slit separation, wavelength, and fringe spacing | Apply principles of constructive and destructive interference to predict diffraction behavior
