Diffraction

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.
Diffraction

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

Compute a diffraction pattern for a single slit:

single slit diffraction d=1/16 inch, lambda=200nm
single slit diffraction Rayleigh angle

Compute a diffraction pattern for a circular aperture:

circular aperture a=0.2mm, lambda=650nm

Explore the diffraction pattern and maxima for multiple-slit diffraction:

4-slit diffraction with slit width 0.05 mm

Calculate the features of diffraction gratings:
