About this Simulation

This simulation models single slit diffraction and two-source optical resolution using wave superposition principles. Students can adjust slit width, wavelength, and source separation to observe how diffraction patterns change and explore when two point sources become distinguishable according to the Rayleigh criterion.

Learning objectives: Understand how single slit diffraction affects optical resolution | Apply the Rayleigh criterion to determine when two light sources can be resolved | Investigate the relationship between wavelength, slit dimensions, and diffraction pattern visibility
