Development of light polarization experimental apparatus for remote laboratory in physics education

Abstract

This paper describes the development of a light polarization experimental apparatus for a remote laboratory. The apparatus had been developed by controlling the analyzer rotation using a stepper motor controlled via the Arduino. Device control and data acquisition applications were developed with LabVIEW which provides remote control panel facilities and web publishing tools. With the developed apparatus, light polarization experiments about Malus’s law in physics teaching can be carried out remotely via the web. The results of the remote experiment show a good agreement with the theoretical predictions. It is concluded that the apparatus for remote laboratories is suitable for use in online experiment-based physics teaching

“…Low cost Physics experiments give students the chance to work in a way that suits their cognitive style, to try it on their own, to adapt their own hypotheses about the problems, and to develop their own problem-solving methods (Josey, Alvi, Kattayat and Asha, 2018). The importance of using low-cost materials is emphasized as well in other studies related to the Malus' law experiment (Çolak and Erol, 2020;Ishafit et al, 2021;Kadri et al, 2014;Kostan et al, 2018;Monteiro et al, 2017;Rosi and Onorato, 2020;Tavares and Muramatsu, 2008).…”

“…Light polarization is an abstract concept in physics (Mataubenu and Langtang, 2018) and is one of the difficult issues of optics (Garg, Sharma andDhingra, 2011, Çolak andErol, 2020). However, learning the polarization of light is very important because of its contribution to the development of science and technology (Ishafit, Mundilarto, and Surjono, 2021). Malus' law explaining the polarization of light is an elementary area for experiment in the optical laboratory, and for students' scientific learning (Tavares and Muramatsu, 2008).…”

“…In the experiment, a step motor controlled by Arduino was used for rotating the analyzer, and a graphical user interface developed with LabVIEW, for device control and data acquisition. According to the researchers, this device is also suitable for use in physics teaching in online experimentation through the installation of a webcam in a remote laboratory system (Ishafit et al, 2021).…”

Archimedes’ principle experimental apparatus for remote physics laboratory

“…After publishing, users can access the system and its apparatus via the website. The architecture of remote laboratory system (see figure 6) used in this experiment is as described in [13]. The experimental apparatus is connected to a computer on a lab server.…”

Low-cost and easily replicable apparatus: an Arduino controlled device for educational activities focused on measuring Brewster’s angle

“…As they are based on electronics and programming, the use of Arduino boards is ideal for projects that aim to integrate the areas of science, technology, engineering, and mathematics, including nanotechnology [8]. In optics, specifically for topics involving light polarization, we can highlight the didactic applications of the Arduino platform mainly in experiments on Malus's law [9,10]. On the other hand, there are few reports on the use of Arduino to teach polarization of light.…”
