Spektroskopiden güneş gözlüklerine kadar geniş bir uygulama yelpazesine sahip olan ışığın kutuplanması olayı, ışığın dalga karakterinin en iyi temsillerinden biridir. Işık şiddeti ile polarizör ve analizörün iletim ekseni arasındaki açı arasındaki ilişki Malus yasası kullanılarak açıklanabilir. Bu çalışmada, Malus yasasını kanıtlamak için basit araçlar kullanarak tasarlanmış bir deney sunulmaktadır. Deney, ışık geçirmez ortam oluşturmak için kullanılan ve içerisine bir analizör, bir polarizör ve bir LDR yerleştirilmiş bir ışık geçirmez kutu, LDR’den gelen verileri toplamak için kullanılan bir mikrodenetleyici olan Arduino Nano ve toplanılan verilerin analiz edilerek grafiğe dönüştürülmesinde kullanılan, araştırmacılar tarafından geliştirilmiş, Işığın Polarizasyonu (PoL) uygulamasından oluşur. Deneyde Android işletim sistemine sahip bir telefon ekranında, gerçek zamanlı olarak, ışık şiddetinin açıya bağlı grafiği çizdirilmektedir. Deney, araştırmacıların ve öğrencilerin, Malus yasasına göre analizör ve polarizör eksenleri arasındaki açı değişimini, ışık şiddeti ile doğrudan ilişkilendirmelerine olanak tanımaktadır.

AN ARDUINO BASED EXPERIMENT TO PROVE AND TEACH MALUS’ LAW

Öz

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.
