We investigate diffraction of a white beam in a two-dimensional photonic crystal. Experimental and computational results for a halogen light source are presented. Applying equal-frequency surface analysis, we reproduce the experimental results by computer simulations. The white beam is modeled computationally as a sum of many circular rings; each ring is made up of many wavelength components. We also present computer simulations of the diffraction pattern for a fluorescent light source.
