Consider two adjacent transparent media. the speed of light through medium 1 is vi, and the speed of light through medium 2 is ½. if vi < v2, then total internal reflection will occur at the interface between these media if a beam of light is 0 a. incident in medium i and strikes the interface at an angle of incidence greater than arcsin vi/v2) b. incident in medium 1 and strikes the interface at an angle of incidence greater than arcsin(2/vi) ° c. incident in medium 2 and strikes the interface at an angle of incidence greater than arcsin(vi/v2). d. incident in medium 2 and strikes the interface at an angle of incidence greater than arcsin(v2/vi).
