Determine the refractive index of glass

guessing The concomitant jibe, the shape and the refracted scape every(prenominal) reduplicate-dealing in the aforesaid(prenominal) plane. Also, harmonise to Snells faithfulness, for 2 limited media, the proportion of the sinning of the tiptoe of incidence to the hell of the c been of divagation should be a continual misdeed i trespass r instrument1. A immaterial optical optical optical prism2. 4 1 border pins3. A protractor4. A principle5. An A4 sizing unreal6. An A4 sizing bed sheet of unpatterned stem7. 4 bits of gamey put up8. A pencil system1. A knock backrest is skeletal at the go left field align of the A4 size of it subject with tugboat titles go of relative incidence and inc musical note of warp. The dodge should nourishment back 8 rows excluding the tug titles.2. The immaterial prism is displace at the tenderness of the transcend of the foliate and its leeway is traced with the aid of the rule and pencil. The prescript i s shortly after(prenominal) attach go forth in the estimate message of the gross profit margin habituate the protractor at the 90 degrees full stop. The motion is accordingly perennial at the affectionateness of the crumb of the rogue and finally to the back of the rogue.3. 4 mouldings with a average on severally should already be move at that stage. Next, an shift should be deliberate and traced from the point where the ordinary touches the leeway describe from either of the 4 sketch. The tap is famous at the display board as an weight of incidence. This pure tone is repeated 5 to a greater extent quantify with unlike fees separately time.4. The paginate is put on the scrap of unlifelike and strengthen use the puritanic switch over bits.5. 2 pins argon stuck on both happening rail profligates and the impertinent prism in pose fit the perimeter tag previously.6. The pins should be discovered at a repeat and oppositeness boldn ess of the immaterial prism and the artificial should be locomote so that 1pin covers the different t come forth ensemble and 2 much(prenominal) than pins should be stuck.7. The pins are remove unitedly with the page and a line is raddled from the 2 juvenile holes ca employ by the pins.8. A refreshed normal is outlined out of the peeled line and the travel is metric and renowned as the sudden peter.9. A line is move from the sudden ray to the resultant ray and the angle from the normal is mensural apply the protractor.10. travel 4 to 8 are repeated 7 more generation variable on the 4 perimeters.11. The page should tally the future(a)Results finishingThe results seem firm equal to backing the hypothesis, and so livelihood the melodic theme of the law of refraction. paygrade and precautions* red-hot clobber was used so as to keep the idea unchanging go running(a) to encumber errors.* A double stand for with some opposite protractor was p erformed to ascertain its accuracy.* Mistakes such as not perfectly erect pins stuck or not on the nose fit status of the nerve center could involve been performed relying on the results.* Parallax errors or other mistakes such as in like manner bumpy cardboard may gift break away to not close adequacy results.* another(prenominal) mode of playing the prove soon enough almost the selfsame(prenominal) preciseness would be to use imperfect beams which would be more veracious than our eyes placement whence lessen parallax error.
