Light Interference from a Soap Film: A Revisited Quasi-Monochromatic Experiment
Rosi, Tommaso; Gratton, Luigi M.; Onorato, Pasquale; Oss, Stefano
Physics Education, v54 n1 Article 015018 Jan 2019
We propose to reconsider the well-known experiment about the interference of white light from a thin soap film by adopting as an illuminating source the RGB triad produced by a LED projector. The interference pattern shows up in a particularly fascinating way and it contains direct, essential information about both the wave nature of light and of the physical thickness of the soap film.
