...has its direction changed at the common surface of the two mediums, it is said to be refracted. S. The angle contained between the incident ray and the perpendicular to the reflecting, or refracting, surface at the point of incidence, is called the angle of incidence. 4.

...objects. they receive, we perceive their own forms, colours, and appearances. It must be observed, that the angle contained between the incident ray and the perpendicular to the reflecting surface at the point of incidence, is called the angle of incidence. BOA, fig. 1, is the angle of incidence... | |
