light travels from ethanol intro crown glass. what's the brewster angle in this situation? illustrate your answer with a light ray diagram. what's the signifcance of this angle of incidence?
nR=1.52 for crown glass
=1.12 (48.2 degrees)
the only thing that I have in the diagram is the face that both the incident and reflected rays are 48.2 degrees in the ethanol..not even sure if that is right.
not sure how to draw it or what the signicance is....please explain.

Bob - I looked at the website you gave me. In order to draw it, do I need to also figure out the angle of incidence and reflection? If so, how do i do that...thanks
WEll, you have the angles of incidence of 48.2, so use snell's law to get the angle of refracation.
