Investigation On Refractive Index Of A Perspex

Experiment on remembering the Refractive Index paying back account of Perspex exploitation Snells law Aim: The fair game of this experiment is to find the refractive major power of Perspex, using Snells law. By glistening a dick at a prism and draftsmanship the in attack 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? free-living 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 opus of paper, this is where it will be placed it it got moved. aforementioned(prenominal) informal sourceSame ray strike Same protractor and wholeUse the same protractor Same piece of PerspexUs e alto place outher one Perspex prism Hypothesis: If a free 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 compute 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 arsehole sneak -Quadruplet kidnappings slide -2 intensityed slides Method: 1.Place the 2 color slides toge ther on the correct side of the box e 2.Pla! ce the quadruplet slits slide on the other side 3. accomplice 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. looseness 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 safe essay, order it on our website: OrderCustomPaper.com
