Diffraction grating slide for optics demonstrations The Demo Diffraction Grating gives students a whole new view of diffraction, making one of the most fundamental—and traditionall y difficult—optics concepts clear and accessible. This demonstration slide features three diffraction gratings with 100, 300, and 600 lines per millimeter, all mounted between protective glass plates. With multiple grating densities on a single slide, students can easily compare diffraction patterns and explore how slit spacing and wavelength affect light behavior. Why Teachers Love the Demo Diffraction Grating Three gratings in one slide: Quickly compare diffraction patterns using 100, 300, and 600 lines/mm. Easy classroom setup: Eliminates the complexity of swapping gratings or reconfiguring lab setups. Clear, large-scale demonstrations: Diffraction patterns are easy to see and analyze. Supports quantitative labs: Enables precise wavelength measurements and pattern analysis. Durable construction: Glass-mounted gratings protect the optical elements for long-term classroom use.
