Brewster’s law in the light of the refined unambiguous angles of incidence, reflection, and refraction

Abstract

This paper reports on the discovery of ambiguity in the traditional definition of the Polarizing angle (also called the Brewster’s angle) as well as that in the traditional Brewster’s law, since both of them are based on the long-running concepts of angles of incidence, reflection, and refraction, each of which has been reported to be ambiguous in 2005 by the author. With the incorporation of the refined unambiguous angles of incidence, reflection, and refraction, reported by the author in 2015, unambiguous definition of the Polarizing angle (or the Brewster’s angle) as well as the unambiguous statement of the Brewster’s law have been offered along with the accomplishment of relevant proof.
