Can You Master Drawing Ray Diagrams for Prisms Using Snell's Law?

How to draw ray daigrams for prisms.

At the air to glass interface (ray entering the prism) the ray refracts towards the normal and again away from the normal when it exits (ray traveling from glass to air). If one knows the refractive index the angle of refraction can be calculated.
