We present an educational double-slit experiment aimed at strengthening students’ ability in physical reasoning, both from a theoretical and an experimental perspective, while improving their understanding of interference/diffraction phe- nomena. In particular, students are lead to focus their attention on the hypotheses employed in the reference theoretical model (i.e., Fraunhofer or far-field diffrac- tion), and are guided to build an experimental setup that satisfies such conditions. For completeness, we also present some quantitative results based on two different measurement techniques: The direct measurement of intensity versus position, and digital photography.

Abstract

We present an educational double-slit experiment aimed at strengthening students’ ability in physical reasoning, both from a theoretical and an experimental perspective, while improving their understanding of interference/diffraction phe- nomena. In particular, students are lead to focus their attention on the hypotheses employed in the reference theoretical model (i.e., Fraunhofer or far-field diffrac- tion), and are guided to build an experimental setup that satisfies such conditions. For completeness, we also present some quantitative results based on two different measurement techniques: The direct measurement of intensity versus position, and digital photography.
