Double-slit diffraction intensity pattern

Description

This animation illustrates the evolution of the double-slit diffraction intensity pattern as the slit separation varies from 300 µm to higher values. The intensity profile along the position axis transitions smoothly, revealing how increasing slit separation compresses the interference fringe spacing while maintaining the overall envelope of the single-slit diffraction pattern. These dynamic changes highlight the inverse relationship between slit separation and fringe width, consistent with the principles of wave interference in optics.
