Reflection modeled with the Huygens Principle
Storyboard 
If the wavefront is described by multiple sources along the wavefront, it is observed that when the system interacts with an edge, new sources are generated along it, which in turn generate a new wavefront that propagates in The second medium. Given the difference in velocity in each medium, the second wavefront undergoes an offset that leads it to propagate with a different angle of refraction than the incidence.

Principio de Huygens y reflexión

Para el caso de la reflexión se puede trabajar con el principio de Huygens. Para ello se localizan en forma equidistantes fuentes que son activadas a medida que la onda incidente las alcanza generándose el nuevo frente de onda que tiene el mismo angulo de reflexión que aquel con que incidió:
