Malus Yasasini Kanitlamak Ve Öğretmek Amaciyla Arduino Temelli̇ Bi̇r Deney

Abstract

The polarization of light is one of the best representations of the wave character of light, having a wide range of applications ranging from spectroscopy to sunglasses. The relationship between light intensity and the angle between the transmission axis of the polarizer and the analyzer can be explained by Malus' law. In this study, an experiment is presented that has been designed to prove Malus' law using simple tools. The experiment consists of a lightproof box having an analyzer, a polarizer, and an LDR, to create a dark environment, a microcontroller, the Arduino Nano, to collect data from the LDR and the Polarization of Light (PoL) application developed by the researchers to analyze and graph the collected data. In the experiment, a graph in which the light intensity depends on the angle is drawn in real time on a phone screen with an Android operating system. In the experiment, a graph of the light intensity depending on the angle is drawn in real time on a phone having an Android operating system. The experiment allows researchers and students to directly correlate the angle change between the analyzer and polarizer axes with the light intensity according to Malus' law.
