Diffraction describes the behavior when a wave encounters an obstacle or a slit. Wolfram|Alpha provides tools for computing diffraction patterns for a large range of diffraction obstacles, including single slits, double slits, circular holes, diffraction gratings and more.


Calculate the locations of the maxima and minima and other properties of diffraction patterns.

Compute a diffraction pattern for a single slit:

Compute a diffraction pattern for a circular aperture:
