A ray of light traveling in air makes a 63.0 angle with respect to the normal of the surface of a liquid. It travels in the liquid at a 39.2 angle with respect to the normal.
Find the critical angle for total internal reflection for this interface.
Question 2
A particle physicist observes cosmic rays creating a new particle high in the atmosphere, and the speed of this particle is measured at 99.7 the speed of light.

A) 2.9 s
B) 18 s
C) 5.3 s
D) 12 s
E) 4.3 s
