About this Simulation

This interactive simulation models wave diffraction—the bending of waves around obstacles and through openings. Students adjust wavelength, barrier separation, and observation position to visualize how diffraction patterns emerge from wave superposition. Real-time visual feedback demonstrates the relationship between wavelength scale and diffraction intensity.

Learning objectives: Understand how waves diffract around barriers and through slits | Predict diffraction pattern intensity based on wavelength and barrier geometry | Apply superposition principles to explain constructive and destructive interference in diffraction
