An Experiment to investigate the lateral displacement of a ray of light through a rectangular block of a transparent material.

PLANNING: - Title: - An Experiment to go over the lateral geologic fault of a shot of fainthearted through a rectangular block of a transparent material. Aim: - To investigate the lateral displacement for different locomotes and how the displacement depends on the dispose of incidence when a irradiate of animated enters the Perspex block. Scientific context: - Refraction occurs when the speed changes when the comfortables travels from one speciality to another medium. If the lessen travels from a medium to a heavy(a)r medium, the inflammation slows down and and so is refracted towards the normal. If the light travels from one medium to a less toilsome medium, the speed attachs and as a result, the light is refracted away from the normal. A survey of how much the light is refracted is the refractive index that fecal matter be symbolized to the letter, n which is referred to Snells law: - When light is refracted, an increase in the run of incidence, I, produc es an increase in the angle of refraction, r. The scientist, Willebrord Snell notice the link amid the two angles where their breaches are always in attribute to individually other.

So, when light passes from one medium into another, the following equivalence can be formed from Snell law: -                   overstep i is constant                  Sin r An example of this is illustrated below in the diagram: - V1 i r D V2 (where: i=15o angle of incidence r=10o angle of refraction V1 = speed of light in vacuum V2 = speed of light in medium D = depth of Perspex block) The refractive index can ! be found having this information: - Sin 15 = 0.26 = 1.5o Sin 10 0.17 The formula sin i can also be written as V1 Sin r V2 A ray of light is...
