and during the 16th and 17th centuries there were conflicting theories which regarded light as either a wave or a particle. The first discovery of electromagnetic radiation other than visible light came in 1800‚ when William Herschel discovered infrared radiation. The next year Johann Ritter discovered ultraviolet radiation. Electromagnetic radiation had been first linked to electromagnetism in 1845‚ when Michael Faraday noticed that the polarization of light traveling through a transparent material

CHAPTER 1 INTRODUCTION At first glance the idea of running an engine on air seems to be too good to be true. Actually‚ if we can make use of air as an aid for running an engine it is a fantastic idea. As we all know‚ air is all around us‚ it never runs out‚ it is non-polluting and it is free. An Air Driven Engine makes use of Compressed Air Technology for its operation. Compressed Air Technology is now widely preferred for research by different industries for developing different drives for different

Osteoarthritis is a progressive form of arthritis which is characterized by breakdown of the cartilage in joints [1]. Osteoarthritis is abbreviated as OA and is also known as degenerative joint disease. Osteoarthritis will cause pain in the joints with activity. The knees and the hips are common joint locations that are affected with osteoarthritis. Osteoarthritis is common in people over 60 years of age‚ but it can affect younger people when they have had joint injury or surgery [2]. Osteoarthritis

Abstract The bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure and its mechanism. After the addition of bromine to trans-cinnamic acid‚ the product was identified by its melting point and infrared spectrum resulting in erythro-2‚3-Dibromo-3-phenylpropanoic acid after comparing similar properties. Introduction In this lab‚ the bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure‚ and from there determine

The hotter an object is‚ the more infrared radiation it emits. This infrared radiation can be reflected by shiny surfaces. Infrared radiation is absorbed best by black‚ dull - not shiny - surfaces. Infrared radiation is a type of electromagnetic radiation. It involves waves‚ rather than particles. Unlike conduction and convection‚ radiation can

The phenol group of methyl salicylate is a weak acid‚ therefore it reacts very swiftly with a strong base‚ in this case NaOH‚ to form a sodium salt. Which removes the H from the phenol group. During hydrolysis the ester group of methyl salicylate is broken apart by the addition of a molecule of water. From which a molecule of alcohol and a molecule
