Designing an Experimental Prototype to Support Geometric Optics Concepts Comprehension

Abstract An experimental prototype to support the comprehension of concepts of Geometrical Optics was designed and assembled. The prototype might help teachers to explain Geometrical Optics concepts -for example, the behavior of light passing through converging and diverging lenses and optical instruments-, it is an inexpensive and accessible device that can be transported to classrooms. The expectation is that the equipment, properly used by teachers, would lead the students to understand abstract concepts of Geometrical Optics and thus motivate them to study this science
