Uma proposta de ensino de ótica com material de baixo custo: a interferência da luz com o Espelho de Lloyd

Abstract

The Education in Brazil has always been inserted in an environment full of change economic, social or cultural where reformulations and changes until today must be realized for it to be perfected. The teaching of physics is one of the segments of education that can, and needs to be improved, as an alternative that allows a change in the technical and repetitive model still present in physics teaching we have as a tool the use of low cost experiments, which aims to contextualize and motivate students in understanding that subject. The proposal presented is that of an experiment related to physical optics, a little worked area in high school, where a theoretical and experimental presentation will be made to enable teachers to present an adequate explanation for light interference and to enable them to reproduce in the classroom using low cost materials the experiment performed by Lloyd, where it is possible to observe the light interference, as we have in the experiment performed by Young.
