A laser beam is incident on a 60°–60°–60° prism. It makes an angle e with the normal, as shown in Figure 1. The transmitted beam that exits the prism makes an angle ô with the direction of the incident beam. 60° Figure 1 (i) Derive the formula that relates the index of refraction of the prism and angle of incidence, 0, and angle of deviation, 8. (ii) If 0 = 20.0° and ô = 30.5° , find the index of refraction of the prism. %3D %3|
