Using Tracker to find the minimum angle of deviation and the refractive index of a prism

Abstract

Abstract The target of this study is to determine the minimum angle of deviation of a prism which is one of the optical experiments. Thus, the aim is to state the refractive index of a prism. In this context, the Tracker program, which might also be utilized in terms of distance education purposes, was preferred. The videos of the experiments were recorded with the help of a smartphone. The study showed that the refractive indexes of the prisms which were made of glass and acrylic with different apex angles could be determined with a high level of accuracy as a result of the analysis of videos which were recorded with two different methods. It is believed that the study provides insights for both the conduction of laboratory courses via distance education and for performing experiments for students who do not have access to proper laboratory equipment.
