3, the angle of incidence ([[theta].sub.i]) is calculated by the inner product of the unit direction vector (i) of the incidence photons and the unit normal vector ([[vector].n]), and the angle of refraction ([[theta].sub.r]) is calculated by "Snell's Law".
As these two beams exit the crystal they are bent into two different angles (known as angle of refraction) because the angle is affected by the speed of the beams.
