Proposta de sequência didática para aula experimental de difração e interferência da luz

Abstract

Experimental classes are an important pedagogical resource in the teaching-learning process of Physics. In addition to making this process more efficient, they provide a more complete scenario of Physics because this science has a strong empirical basis. However, due to various reasons such as lack of resources or lack of time during classes, a significant number of teachers still opt for excessively theoretical classes, presenting physical phenomena only by means of equations, images, drawings and diagrams. This can be supported by the analysis of textbooks as well as articles about the subject, where the lack of teaching materials that encourage the practice is explicit. This work proposes the elaboration of a didactic sequence for Optics classes in high school, focusing on Thomas Young’s double slit experiment. The experimental practice proposed here allows students to carry out the experiment with a quantitative approach, enabling the handling of measuring equipment and instruments. The necessary materials are cost-effective and easy to find, making it possible to carry out the practice in places not adapted for experimentation.
