## θ_{brewster} = arctan(\frac{n_2}{n_1}) ##
The Attempt at a Solution
Hi all
I'm having difficulty on this part of a question Now, showing that all light passes through is to say that there be no reflection. This occurs when the angle of incidence on each of the two interfaces is at the required Brewster angle. As in the question, there will be no reflection at the first interface by definition since the beam is incident at the Brewster angle. For there to be no reflection at the second interface, it must be incident at ## θ = arctan(\frac{n_{air}}{n_{glass}}) ##. However, how can I prove that this is the case? Snell's law shall of course come into play.
Many thanks
