Abstract (English): This article presents the development and application of an interactive computational simulator of single-slit and double-slit interference and diffraction phenomena, using red, green, and blue laser sources. The tool was developed in Python and allows for the alteration of optical parameters such as slit width, distance between slits, distance between the slit and the screen, and the type of light source. The simulator was designed to overcome limitations in teaching laboratories, especially the scarcity of lasers with different wavelengths, which hinders the experimental comparison of the patterns formed. The results obtained demonstrate that the simulation constitutes an efficient teaching resource for visualizing the wave behavior of light, suitable for use in both in-person and remote optics teaching activities.

Abstract (Portuguese): Este artigo apresenta o desenvolvimento e aplicação de um simulador computacional interativo dos fenômenos de interferência e difração por fenda simples e dupla, utilizando fontes de laser vermelho, verde e azul. A ferramenta foi desenvolvida em Python e permite a alteração de parâmetros ópticos como a largura de fenda, a distância entre fendas, a distância entre fenda e o anteparo e o tipo de fonte luminosa. O simulador foi concebido com o objetivo de suprir limitações existentes em laboratórios didáticos, especialmente a escassez de lasers de diferentes comprimentos de onda, o que dificulta a comparação experimental dos padrões formados. Os resultados obtidos demonstram que a simulação constitui um recurso didático eficiente para a visualização do comportamento ondulatório da luz, adequado para uso em atividades presenciais e remotas de ensino de óptica.
