In the Classroom
Tested Demonstrations
Using Lasers to Demonstrate Refraction, Diffraction, and Dispersion
Elvin Hughes, Jr. and L. H. Holmes, Jr.
Department of Chemistry and Physics, Southeastern Louisiana University, Hammond, LA 70402

March 1997
Vol. 74 No. 3
p. 298
Abstract
Using a red and green laser the phenomenon of refraction and diffraction can be demonstrated relatively easily in the classroom. Also the difference in dispersion with a prism (normal dispersion) and dispersion with a grating (which follows the Bragg equation) can be shown.
