Laws of reflection and Snell’s law revisited by video modeling
Author(s): M. Rodrigues; P. Simeão Carvalho

Paper Abstract

Video modelling is being used, nowadays, as a tool for teaching and learning several topics in Physics. Most of these topics are related to kinematics. In this work we show how video modelling can be used for demonstrations and experimental teaching in optics, namely the laws of reflection and the well-known Snell’s Law of light. Videos were recorded with a photo camera at 30 frames/s, and analysed with the open source software Tracker. Data collected from several frames was treated with the Data Tool module, and graphs were built to obtain relations between incident, reflected and refraction angles, as well as to determine the refractive index of Perspex. These videos can be freely distributed in the web and explored with students within the classroom, or as a homework assignment to improve student’s understanding on specific contents. They present a large didactic potential for teaching basic optics in high school with an interactive methodology.
