Description

Hold a small (approximately 1" x 1 1/2") replica grating about an inch in front of your eye and look off to the side to see the spectrum. The gratings are cut from a roll of 13,200 line per inch replica grating material, and are very cheap, so they can be given to the students to keep as souveniers of their physics experience at the University of Maryland.
