About

Grating Simulator

Features
Read full description

The laser interference pattern is similar to what would be produced by a Laser pointer’s beam passing through a diffraction grating – When you shine a laser pointer (green, 532nm wavelength) through a series of transmission diffraction gratings, you get a beautiful regular array of bright spots. The center spot is the zero-order (undiffracted beam), and the surrounding spots are the various diffraction orders. The symmetry and regularity of the pattern is characteristic of a diffraction grating pattern. This simulation could be used as a demonstration setup for physics education – teaching about wave optics, interference and diffraction. It is a classic physics demonstration that beautifully illustrates the wave nature of light and the principles of diffraction.
