Abstract

A procedure for observing diffraction from a circular aperture using photography equipment and commonly available light sources is presented. Commonly called the Airy pattern, such a diffraction pattern is characterized by a central bright spot, with concentric bright and dark rings. The images obtained in this procedure are suitable for discussing and demonstrating Rayleigh's criterion in introductory physics classes. It is shown that the patterns observed change as expected with wavelength and aperture.
