Gratings: Diffraction Grating and Laser

Photo of the Demonstration at the University of Texas at Austin.

Instructions / Notes:

• A laser is projected through an 80 lines/mm diffraction grating.
• The laser then can be projected through a 100 lines/mm grating, along with a 300 lines/mm and a 600 lines/mm grating for comparison.
