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 enquire the lateral geological 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 slant of incidence when a ray of animated enters the Perspex block. Scientific priming coat: - Refraction occurs when the speed changes when the comfortables travels from one medium to another medium. If the take fire travels from a medium to a heavy(a)r medium, the illuminance slows down and consequently is refracted towards the normal. If the light travels from one medium to a less bleak medium, the speed pluss 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 faecal matter be symbolized to the letter, n which is referred to Snells law: - When light is refracted, an increase in the go of incidence, I, produc es an increase in the angle of refraction, r. The scientist, Willebrord Snell sight the link amid the two angles where their breaches are always in symmetry to individually other.

So, when light passes from one medium into another, the following equality 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 Pe rspex block) The refractive index can be fo! und 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...
