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.

Abstract
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.| File | Dimensione | Formato | |
