The Critical Angle for Total Internal Reflection Is A

Multiple Choice

The critical angle for total internal reflection is a:

A) is a single angle for which transmission through the boundary is zero
B) a maximum angle of incidence,below which no light is transmitted through the boundary
C) minimum angle of incidence,above which no light is transmitted through the boundary
D) may be either a minimum or a maximum angle,depending on which of the indices of refraction is larger
