WebReflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common … WebLight rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in …
