The refractive index of plastic using Snell’s Law is: 1.344 ± 0.06. g [11][12][13] Polymers with sulfur-rich thianthrene and tetrathiaanthracene moieties exhibit n values above 1.72, depending on the degree of molecular packing. o Learn the basics with our essay writing guide, Name Jonathan Tam Class: 13A, Yew Chung International School Physics, Aim: Find the refractive index of a plastic block. p Each material in the database has refractive index listed as a function of wavelength over a range typically required for thin-film thickness measurement. "Characterization of Biaxially-Stretched Plastic Films by Generalized Ellipsometry" Thin Solid Films 1998, 313/314, 814-818. TASK 3: Set the angle of the raybox by rotating it with the red handle or setting the angle with the raybox input field. Set up the apparatus as shown. PS - Polystyren Get Full Access Now
Use the protractor to check the angle that you have set. or exits the lens, with Snell’s Law (eq 2.2 below) giving us the , where TurnItIn – the anti-plagiarism experts are also used by: Want to read the rest? Cellulose Refractive Index Database The table below contains links to refractive index data for common materials. n o Many materials have a well-characterized refractive index, but these indexes depend … METALS [4][5], As of 2004, the highest refractive index for a polymer was 1.76. Many 3d applications these days allow you to input actual IOR values in order to achieve a more accurate representation of surfaces during rendering of your 3d models. In general, high molar refractivity and low molar volumes increase the refractive index of the polymer. Repeat step 3 to 6 at least 7 times to get sufficient readings. [1], Such materials are required for anti-reflective coating and photonic devices such as light emitting diodes (LEDs) and image sensors. [14] However, recent applications of halogen elements in microelectronics have been severely limited by the WEEE directive and RoHS legislation adopted by the European Union to reduce potential pollution of the environment. The Michael polyaddition is used for a polyimide because it can be carried out at room temperature and can used for step-growth polymerization. The sample should have at least one flat polished face. Put a piece of white paper under the apparatus. index in the two materials across the boundary of which the ray is [15], Phosphorus-containing groups, such as phosphonates and phosphazenes, often exhibit high molar refractivity and optical transmittance in the visible light region. JavaScript seem to be disabled in your browser. The choice of nanoparticles is often influenced by their size and surface characteristics. MAIN - simple inorganic materials This is called refraction. CRYSTALS There are many systematic errors in these experiments, which came from the apparatus itself. * Some of the plastic trays have bumps on the bottom. To increase the reliability of my results I would use fresh paperclips after each test because I believe that a paperclip that has just been used in a test still has a magnetic charge left over and so if used again would distort the results. The refractive index of a transparent material is a fundamental of that material and can be used to identify the material. PC - Polycarbonate The refractive index of a material is defined as the ratio between the speed of light in a vacuum(c) and the speed of light in that material (cm). Refractive Index Database The table below contains links to refractive index data for common materials. [CSV - comma separated] n {\displaystyle {n_{comp}}={\Phi _{p}}{n_{p}}+{\Phi _{org}}{n_{org}}} [18] Shaver et al.
Φ As light travels into a denser medium it causes the wave length to change but the frequency of the wave never changes.
