Finding Brewster's Law - Relation between Io and Refractive Index n

[llewyn]

Homework Statement

Using your knowledge of perpendicularity between the reflected and refracted rays at the polarising angle, find brewster's law, a relation between Io (the angle to the normal) and the refractive index n. The relation consists of no other variable or physical constant


No idea what to do here any help?
