A sequence of experiments and models to grasp the strange nature of light

We present a sequence of activities designed to stimulate students reflect on the nature light and different models (ray, wave, classical quantum particles) used in teaching learning optics. These are also aimed help evaluating profound meaning "correspondence principle" develop their own views about some aspects science even if it is not taught explicitly. In fact, optics paradigmatic case where scientific proposed University (and high school) courses. Even oldest these have non empty domains validity both Maxwellian electromagnetism geometrical largely still Physics curricula. As consequence often puzzled, think that each theories works specific domain, without any connection one with other. Thus we investigate students' mental contexts show how they hybrid explaining phenomena or use inconsistently.
