Construction of an automated experimental model for the study of light polarization and experimental proof of Malus' Law with the aid of the Arduino platform

Abstract

In this article, we present the necessary procedures for the construction of an automated experimental model to prove the Malus law with the aid of the Arduino platform, in line with the automation plan for laboratory practices at the General Physics Laboratories of the State University of Southwest from Bahia, UESB. The choice of the Arduino platform is primarily related to its low cost, ease of programming and its ability to study physical processes in real time in educational practice, which has allowed the modernization of laboratories, which are automated, manipulated remotely. The use of modern software and hardware resources, united by a universal software platform, allows the creation of virtual and real multifunctional tools with a comfortable interface for students and researchers. The experimental results obtained were used to demonstrate Malus' law by two methods. In fact, considering the latest advances in computer technology, there are real opportunities to introduce the most advanced and efficient software and hardware resources, highly interactive without the use of expensive equipment.
