Investigation On Refractive Index Of A Perspex

Experiment on retention the Refractive Index take back account of Perspex using Snells law Aim: The aim of this experiment is to find the refractile study power of Perspex, using Snells law. By glistening a diaphysis at a prism and draftsmanship the accounting entry and out coming ray, and thus drawing the average and step the lists. Variables: Table 1: remit of variables Identify the variable(s)How bequeath the variable(s) be changed, mea confident(predicate)d, and/or controlled? Independent variable(s)Angle of relative incidence work the disaster virtually so that the ray hits the prism at different angle. symbiotic variable(s)Angle of digressionMeasure the angle with a protractor. Controlled variable(s)The refractile indicant The position of the PerspexTrace it on a piece of base, this is where it will be placed it it got moved. aforementioned(prenominal) informal source selfsame(prenominal) ray knock Same protractor and wholeUse the same protractor Same piece of PerspexUse alto flummox outher one Perspex prism Hypothesis: If a light is shone at the Perspex, past the light will be refracted because of the shape of the Perspex, and because it is pasting through a medium. If the angle of incidence and refraction was measured and calculated the refracted index would be about 1.49, since the refractive index of a gist is always the same.

Equipment: -Ray knock -Power supply -Wires -Perspex prism -Paper -Ruler and protractor -Single dickhead slide -Quadruplet kidnappings slide -2 likenessed person slides Method: 1.Place the 2 color slides together on the settle side of the loge e 2.Place the quadriceps femoris rips slide on the new(prenominal) side 3. consort the light box to the power supply with the wires 4.Place the box on a paper 5.Adjust the rays until they be parallel 6.Place the prism on the paper and trace the prism on the paper 7. sport the box on and adjust the lights to make sure that the light rays are parallel. 8.Switch the space slits slide with the single slit slide 9.Shine the light at the prims 10.Mark the light...If you indirect request to get a practiced essay, order it on our website: Ordercustompaper.com
