Lab 6 - Optics Introduction Geometric optics is one of the oldest branches of physics, dealing with the laws of reflection and refraction. The relationship is known as Snell's Law which states that a ray of light bends in such a way that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is in the same ratio as the velocity of light in the incident medium to the velocity of light in the refracted medium: = = . It is actually a great method to get all the info that you desire, without needing to spend any money. When the light passes from a material of high index of refraction to low index of refraction, there is an angle at which the light starts to be reflected at the interface of the materials.

Ray diagrams for diverging lenses follow similar conventions to those for converging lenses but how the location of the image is determined is slightly different. Snell’s law of refraction was proved by this experiment as the sine of the incidence ray divided by the sine of the reflected ray created a straight increasing line when graphed. This also occurs with light, which is why objects seen across an interface appear to be shifted relative to where they really are.
