Refraction of Light
Season 2 Episode 203 | 28m 29s Video has closed captioning.
Light energy travels in straight lines and in waves. When light strikes a plane or a flat surface, it reflects in a manner that is predictable. For example looking directly into a mirror provides a reflection that is straight back from the source. However if light strikes the plane surface mirror on an angle, then it will bounce of with an equal angle.
