You have two adajacent transparent media. The speed of ligght through medium 1 is v1, and the speed of light through medium 2 is v2. If v1 < v2, then total internal reflection will occur at the interface between these media if a beam of light is
A. incident in medium 1 and strikes the interface at an angle of incidence greater than arcsin (v1/v2)
B. incident in medium 1 and strikes the interface at an angle of incidence greater than arcsin (v2/v1)
C. incident in medium 2 and strikes the interface at an angle of incidence greater than arcsin (v1/v2)
D. incident in medium 2 and strikes the interface at an angle of incidence greater than arcsin (v2/v1)
A. incident in medium 1 and strikes the interface at an angle of incidence greater than arcsin (v1/v2)
