Dvorsky. SNC2D1. Review of last chapter. From the last chapter, we know how light behaves when it travels in space or in the air – i.e. it travels in a straight line.. When light strikes a plane mirror, the angle of incidence = the angle of reflection. . Geometrical optics. , or . ray optics. , describes light propagation in terms of "rays". The "ray" in geometric optics is an abstraction or "instrument", that can be used to predict the path of light.. Refraction occurs at a boundary. The speed of light must change at the boundary. The angle of the light ray is measured from the normal, as was the case with reflection. If the speed slows across the boundary, the refracted angle will be smaller – the light ray will bend toward the normal.. Emmetropia. and the . Ametropias. Scott P. Drexler OD.

What are some examples of refraction of light that show why it is important?. Refraction of Light - Defined. Refraction of light occurs when a light wave moves from a vacuum (or a medium) into another medium (or a vacuum). When a wave changes media, its ____________ changes..
