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 inquire 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 go of incidence when a beam of animated enters the Perspex block. Scientific flat coat: - Refraction occurs when the speed changes when the comfortables travels from one median(a) to another medium. If the cleared travels from a medium to a heavy(a)r medium, the cleverness slows down and hence is refracted towards the normal. If the light travels from one medium to a less vague medium, the speed additions 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 cant over of incidence, I, produces an increase in the angle of refraction, r. The scientist, Willebrord Snell observe the link amid the two angles where their breaches are always in proportionality to individually other.

So, when light passes from one medium into another, the following compare 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...
