A ray of light is incident in medium 1 on a surface that separates medium 1 from medium 2. Let v1, and v2 represents the velocity of light in medium 1 and medium 2 respectively. Also let n12 and n21 represent the refractive index of medium 1 with respect to medium 2 and refractive index of medium 2 with respect to medium 1, respectively. If i and r denote the angle of incidents and refraction, then:
