| Front | Laws of Refraction |
| Back | Law 1. The incident ray, the refracted ray and the normal all lie in the same plane. Law 2: ( Snell’s law ) The sine of the angle of incidence is proportional to the sine of the angle of refraction. |
| Front | Conservation of Energy |
| Back | Energy cannot be created or destroyed but may be changed from one form to another |
| Front | Newton's Third law of motion |
| Back | To every action there is an equal and opposite reaction. Action and reaction do not happen on the same body |
