A didactic reformulation of the laws of refraction of light
In this work, an alternative formulation of the laws of refraction of light is presented. The proposed formulation unifies the two established laws of refraction, and it is shown the correspondence between the new and the classic formulations. This new formulation presents a remarkable didactic interest for the conceptual interpretation and resolution of typical problems related to the phenomenon of refraction of light, such as those proposed to students of geometric optics in their first year of college. As an example, this formulation is applied to the resolution of two refraction problems typically assigned to students of such educational level. Results and comments from the students are presented.
