Lecture-Room Interference Demo Using a Glass Plate and a Laser Beam Focused on It
Ageev, Leonid A.; Yegorenkov, Vladimir D.
European Journal of Physics, v31 n4 p801-809 Jul 2010
We describe a simple case of non-localized interference produced with a glass plate and a laser beam focused on it. The proposed setup for observing interference is compact when semiconductor lasers are employed, and it is well suited for demonstration and comparison of interference in reflected and transmitted light in a large lecture-room. This paper is intended for graduate students as well as for those who teach courses in optics accompanied with cost-effective demos. (Contains 5 figures.)
