Um estudo da luz: construindo com materiais de baixo custo uma Antiluneta Polarizadora e o Sistema Solar

Abstract

The purpose of this work is to present the development of the study of light addressing historical aspects in the creation and evolution of Physics up to our current conceptions; presenting the nature of light and its propagation in refringent means and some aspects of geometrical optics, a polarizing anti-telescope was created, which was applied in the classroom, simulating the reduction of light intensity with the inverse of the distance squared, using lenses and overlapping polarizing blades in PVC pipe, as well as to draw a vision that would have an observer see ingthe Sun in other points of the universe, so that, with this, the student swill understand the Physics present in the current world and in various equipment and procedures. The primary purpose is that this polarizinganti-telescope to be used by the teacher in the classroom, reinforcing students learning and understanding of the physics involved in the mentioned optical phenomenon, which is experienced by them in their every day life, that is, highlighting that this paper presents a proposalfor the reproduction of anti-polarization lenses in the didactic-methodological practices, demonstrating that the use of simple materials can be a creative and instructive alternative for the enrichment of theclassroom and a facilitator for the study of light.
