Light is incident on an equilateral crown glass prism at a thetain = 43.5o angle to one face, as seen in the figure below.
Calculate the angle (thetaout) at which light emerges from the opposite face. Assume that n = 1.52.
ok so i did snells law and found it to be 26.94 deg.
so i know also that a triangle is 180 deg so i should just be able to subtract it all and get the answer
The Attempt at a Solution
well i subtracted it and got 109.56 deg and it was wrong
