An Innovative Polariscope for Photoelastic Stress Analysis Jon R. Lesniak 1‚ Michael J. Zickel1 ‚ Christopher S. Welch2‚ Deonna F. Johnson2 Abstract An innovative polariscope involving a single rotating optical element and a digital camera for full-field image acquisition allows automated data to be acquired quickly and efficiently. Software analysis presents the data in an easy to interpret image format depicting the magnitude of the shear strains and the directions of the principal strains

this experiment‚ we examine the interference and diffraction phenomena of light‚ both of which can be described by the wave theory of light. While interference is just the superposition of waves‚ diffraction is also any deviation from geometrical optics that results from the obstruction of a wavefront of light. In other words‚ diffraction is considering the double-slit experiment by taking into account the width of the slit openings‚ too. Another way of distinguishing between interference and diffraction

Physics Lab report Aammar Paracha Section MX Feb 6th 2015 OPTICS Abstract: This experiment revolves around using light rays and lenses. The experiment also discusses different properties of light rays. This experiment uses different lenses and measurements to produce images and observes different techniques to obtain the image position. Question and Answers: 1. Use your data to verify the Law of Reflection and then use Snell’s Law to calculate

attempts of Wong’s team to launch new product crushed. First of all‚ it can be because of false assumptions (“dangerous assumptions”) that were made by team. That’s why we can conclude that level of uncertainty for new security screeen is rather high and Optic System doesn’t see all opportunities and threats. There is no relevant marketing research for new product. Two main advantages that were found by Noirjean are not sufficient to beat competitors. So‚ it can be that two risks “Existing Competition” and

HISTORY OF FIBER OPTICS * In 1840‚ Daniel Colladon and Jacques Babinet demonstrated the principle of guiding light by refraction. * It was followed by a public demonstration by John Tyndal in 1852. In 1870‚ Tyndal wrote about the property of total internal reflection in his book about the nature of light. * In 1880‚ Alexander Graham Bell and Sumner Tainter invented the Photophone‚ a device capable of transmitting sound waves over beam of light. This is considered as mankind’s first attempt
