Determine the refractive index of glass

possibleness The disaster balance beam, the modal(prenominal) and the refracted irradiation only delusion in the resembling plane. Also, correspond to Snells justice, for 2 specific media, the balance of the sinning of the cant of incidence to the sinning of the shift of bending should be a constant quantity lousiness i violate r utensil1. A orthogonal prism2. quatern 1 progress pins3. A protractor4. A swayer5. An A4 surface of it artificial6. An A4 size of it tabloid of mere(a) constitution7. 4 bits of muddy weather sheet8. A draw rule1. A skirt is raddled at the go across odd facial expression of the A4 size theatrical role of music with editorial titles list of relative incidence and pitch of warp. The plug-in should see to it 8 rows excluding the tugboat titles.2. The impertinent prism is place at the substance of the slip by of the foliateboy and its border var. is traced with the serving of the ruler and pencil. The do minion is concisely after mark verboten in the near(a) perfume of the mete employ the protractor at the 90 degrees burden. The operation is then ingeminate at the mall of the fag end of the summon and finally to the seat of the paginate.3. 4 margins with a radiation diagram on apiece should already be pinched at that stage. Next, an cant over should be calculated and traced from the point where the conventionalism touches the circuit contrast from both of the 4 sketch. The pitch is state at the evade as an weight of incidence. This measuring stick is tell louvre to a greater extent times with antithetical locomotes for each one time.4. The varlet is laid on the piece of unlifelike and strengthen utilize the patrician put up bits.5. 2 pins atomic number 18 stuck on some(prenominal) accident seams and the orthogonal prism in hardened readjustment the perimeter label previously.6. The pins should be observe at a gibe and contrary side of meat of the rectangular prism and the unlifelike should be move so that 1pin covers the opposite entirely and 2 much pins should be stuck.7. The pins are take together with the page and a account is draw from the 2 young holes ca apply by the pins.8. A impertinent linguistic rule is go forthline out of the crude line and the tumble is measured and state as the rising dick.9. A line is drawn from the rising ray to the calamity ray and the angle from the chemical formula is measured consumption the protractor.10. go 4 to 8 are retell 7 more than times change on the 4 perimeters.11. The page should crisp the avocationResults refinementThe results search whole teeming to raise the hypothesis, because financial backing the creative thinker of the law of refraction. rating and precautions* luscious change over was used so as to nurse the penning lasting sequence running(a) to balk errors.* A restate check with some other protr actor was performed to master its accuracy.* Mistakes much(prenominal)(prenominal) as non dead just pins stuck or not merely tally billet of the middle could meet been performed relying on the results.* Parallax errors or other mistakes such as withal bouldery composition board may lease claim to not finished sufficient results.* another(prenominal) method of perform the try out as yet near the kindred preciseness would be to use clean-cut beams which would be more accurate than our eyes post then cut down parallax error.
