Making things look bigger When you use an optical instrument‚ whether it be something very simple like a magnifying glass‚ or more complicated like a telescope or microscope‚ you’re usually trying to make things look bigger so you can more easily see fine details. One thing to remember about this is that if you want to make things look bigger‚ you’re always going to use converging mirrors or lenses. Diverging mirrors or lenses always give smaller images. When using a converging lens‚ it’s helpful

determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X. A microscope must be used to see and study microbes since they cannot be seen with the naked eye. The different combination of microscope lenses allow for smaller organisms to be magnified and seen and studied in greater detail. Procedure: To

Fischer Esterification – nucleophilic substitution reaction Strong acid catalyst (concentrated sulfuric acid Purpose of a reflux is to heat a reaction mixture at its boiling temperature to form products‚ without losing any of the compounds in the reaction flask TO HAVE GREAT PERCENT YIELD: As reaction is reversible‚ removal of water or the addition of an excess of one of the reactants (cheaper one) drives the reaction towards formation of ester. (Excess carboxylic acid is used) Adding excess

Introduction Spectrophotometer is an optical instrument that measures and shows how much light energy is transmitted by a substance in solution at different wavelengths of radiant energy. Light passes into a monochromator where only a very narrow range of wavelengths can pass through. From there‚ light is transmitted through a sample solution‚ and on to a phototube where the light energy is converted to an electric current that is registered on a meter. To measure the amount of light absorbed

Thin Lenses Group members: Trevor Kitts Ryan Mutsch Author: Trevor Kitts 1402L September 10‚ 2012 Introduction In this week’s lab we looked at the movement of light between multiple lenses and their focal points. Procedure List of materials: Optics Bench‚ equipped with laser and triangular like prism. First‚ we aligned the laser with the 0⁰ mark and the center of the prism so that the light hit the bottom of the prism in a perpendicular form. Second‚ we observed that the light

Optical Activity of Carvones Kyle Peterson Chem. 243a Matt Judd‚ Sec. 25 Date Performed: 10/29/03 Abstract: The objective of this experiment is to use Gas Chromatography to distinguish between two enantiomers of carvone from caraway oil and spearment oil and to find the 2 carvone’s optical activity as well as percent carvone in spearment and caraway oil. It was found that S-carvone had an optical activity of 0.0047 and R-carvone had an optical activity of 0.516 and that spearment oil is 59%

LabVIEW (Laboratory Virtual Instrument Engineering Workbench)‚ created by National Instruments is a graphical programming language that uses icons instead of lines of text to create applications. A LabVIEW program consists of one or more virtual instruments (VIs)‚ Virtual instruments are called such because their appearance and operation often imitate actual physical instruments. The objective of developing a virtual interface that acquires data from physical instrument (pH probe) used in the monitoring

Creating optical illusions is an art in itself. And portraying an optical illusion into an aesthetically pleasing work of art requires a fair bit of sense and sensibility. Expressing your artistic skills through illusions calls for the stroke of genius. Literally. In today’s post featured artists have shown their mastery of artistic shapes and colors to produce enlightening as well as scary optical illusions. The post also includes some awesome 3D optical illusions and Jesus optical illusion pictures

Lenses by Annie Dillard Annie Dillard wrote on her experience with analyzing other forms of life. She inadvertently discovered that she and other human beings were not alone in the world. She described her different views of the world by either using a microscope‚ to see a world too small to see with the naked eye‚ or binoculars‚ to see a world that appears to be sightly never ending. Dillard recalls as a child obbessing over watching the algae in her “child’s microscope set”. She was so
