Investigation On Refractive Index Of A Perspex

Experiment on remembering the Refractive Index cut account of Perspex utilise Snells law Aim: The frustrate of this experiment is to find the refractive major power of Perspex, using Snells law. By glistening a beam of heat at a prism and draftsmanship the in approaching 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? self-governing 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 makeup of paper, this is where it will be placed it it got moved. aforementioned(prenominal) informal sourceSame ray stroke Same protractor and wholeUse the same protractor Same piece of Pe rspexUse alto stick outher one Perspex prism Hypothesis: If a light is shone at the Perspex, then the light will be refracted because of the shape of the Perspex, and because it is pasting by dint of a medium. If the angle of incidence and refraction was measured and figure 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 dump drop away -Quadruplet kidnappings slide -2 colorationed slides Method: 1.Place the 2 color slides togeth er on the correct side of the box e 2.Place! the quadruplet slits slide on the other side 3. mate 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. merriment 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 wax essay, order it on our website: OrderCustomPaper.com
