**(a)**

From Brewster's law, the reflected and transmitted rays are perpendicular to each other.

Light travels in a medium with index *n*_{1} toward a boundary with another material of index *n*_{2} < *n*_{1}.

(a) Which is larger, the critical angle or Brewster's angle?

A. Brewster's angle

B. The critical angle

(b) Does the answer depend on the values of *n*_{1} and *n*_{2} (other than assuming *n*_{2} < *n*_{1})?

A. Yes

B. No

(c) What can you say about the critical angle and Brewster's angle for light coming the other way (from the medium with index *n*_{2} toward the medium with *n*_{1})?
