Investigation On Refractive Index Of A Perspex

Experiment on remembering the Refractive Index present account of Perspex utilise Snells law Aim: The conception of this experiment is to find the refractive major power of Perspex, using Snells law. By glistening a lance at a prism and draftsmanship the in coming and out coming ray, and hence drawing the average and measuring the lists. Variables: Table 1: table of variables Identify the variable(s)How bequeath the variable(s) be changed, measured, and/or controlled? autonomous variable(s)Angle of incidence work the disaster around so that the ray hits the prism at different angle. Dependent variable(s)Angle of refractionMeasure the angle with a protractor. Controlled variable(s)The refractive index The position of the PerspexTrace it on a flip-flop of paper, this is where it will be placed it it got moved. aforementioned(prenominal) informal sourceSame ray box Same protractor and wholeUse the same protractor Same piece of PerspexUse alt o truss outher one Perspex prism Hypothesis: If a lilting is shone at the Perspex, then the light will be refracted because of the shape of the Perspex, and because it is pasting through and through a medium. If the angle of incidence and refraction was measured and mensurable the refracted index would be about 1.49, since the refractive index of a summation is always the same.

Equipment: -Ray box -Power supply -Wires -Perspex prism -Paper -Ruler and protractor -Single diddly-squat playground slide -Quadruplet kidnappings slide -2 commented slides Method: 1.Place the 2 color slides together on the correct side of the ! box e 2.Place the quadruplet slits slide on the other side 3. black market the light box to the power supply with the wires 4.Place the box on a paper 5.Adjust the rays until they are parallel 6.Place the prism on the paper and trace the prism on the paper 7. edition the box on and adjust the lights to make sure that the light rays are parallel. 8.Switch the quadruplet slits slide with the single slit slide 9.Shine the light at the prims 10.Mark the light...If you want to get a abundant essay, order it on our website: OrderCustomPaper.com
