Refractive index

is valid and performed accurately. The second part of the experiment focuses on finding the refractive index of the bi-convex lens. This was achieved by using a spherometer. A spherometer measures the radius of a sphere. Both sides of the lens can be considered part of a sphere. The radii of each imaginary sphere can be measured and using the lens maker equation can be used to obtain the refractive index. Image from “university of Sussex physics foundation year laboratory…

product was distilled by using the setup in graph(B.3). When the temperature shown in the thermometer reach 110, four flasks were turning at each 5 degrees Celcius increase interval to retrieve the product distilled in each mini flasks. 12) The refractive index of the product in mini flasks was determined by using the Abbe refractometer.…

1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol by using the Grignard reaction. The product is then determined by spectral…

A comparison will be made between single and multi-mode fiber, emphasizing the advantages and disadvantages of both. Graded-index and step-index are two different types of multi-mode fiber which will be discussed as well as their advantages and disadvantages. The characteristics of multi-mode fiber will be explained as well as what affects the number of modes. Later on in the paper…

rule out sources of error. The need to repeat these measurements can be obtained based upon the HOLLADAY CRITERIA which states: Repeat Km if: Km47D for either eye Difference between the two eyes >1 D Corneal cylinder doesnot correlate well with the refractive cylinder Repeat AL if: AL< 22mm AL> 25mm Difference between the two eyes > 0.3 mm Doesnot correlate well with refraction Repeat all measurements if difference between both the eyes >1D Repeat all measurements if >3d…

glass or water, at the point of penetrating they would suddenly slow down while in the air causing the rays to bend creating refraction. (What is Refraction?, 2016). To indicate how fast every medium waves travel, you will have to use refractive index. Refractive index can measure the ratio of the speed of light in a vacuum to its speed. (Richard Saferstein, 2011).…

Abstract: Fermentation of sucrose with brewer yeast catalyst was successfully conducted to yield ethanol with 70.2 % conversion of sucrose. Based on the graph of Refractive Index vs % ethanol (v/v), 32.8% of ethanol was determined to be in the distillate solution with corresponding Refractive Index of 1.3555 Statement and purpose The purpose of this experiment was to determine the % of ethanol (v/v) in the resulting solution and the % conversion of sucrose Introduction The fermentation 17.1 g…

Q1.Ethernet has become the standard for LAN communications. Give a brief overview of structure of an Ethernet frame. Ethernet and Wi-Fi are the most commonly used technologies to set up Local Area Networks today. It operates by using Carrier Sense Multiple Access Detection (CSMA/CD) to control media access. (Study CCNA, 2016) The structure of an Ethernet Frame is as follows: The Ethernet Frame Structure (Anon., 2013) Explanation: • Preamble: This field is responsible for harmonizing bits…

total http://cablesondemandblog.com/wordpress1/fiber-optic-cables-on-demand/ internal reflection however this can only occur if the optical fibre has a cladding. The cladding of an optical fibre can be made out of any material that has a lower refractive index than the core but is usually made out of plastic or glass. This is because the cladding is used to reflect the light back into the core without losing any energy as well as preventing light leakage. The cladding is then surrounded by a…
