The Laser Diffraction Kit enables students to create, view, and measure diffraction and interference patterns. The kit includes two laser pointers - one red and one green (each requiring two "AAA" batteries, not included) - along with a convenient mounting base and a set of slides featuring diffraction objects. The lasers are Class 3R and each measures 6 inches long by 0.5 inches in diameter.
