Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a & b) are constants

that light behaves as particles. In this experiment‚ an electron was emitted from the metal with a specific kinetic energy. We know that light is a wave because it contains electric fields and magnetic fields. The wave in light is known as an electromagnetic wave‚ and light spreads out from the source that creates the light. The electric and magnetic fields present in light waves obtain a vacuum‚ which makes objects vibrate. The electric and magnetic fields present in the vacuum create the light wave

Teaching Students With Autistic Spectrum Disorders to Read A Visual Approach Leslie Todd Broun As an itinerant resource teacher‚ my ongoing challenge has been the quest for effective methods and materials to meet the needs of my students with autistic spectrum disorders (ASD) and other developmental disabilities. Although the development of communication and social and behavioral skills is crucially important for children with ASD‚ so too is the acquisition of academic skills. Professionals usually

treatments‚ colors can be used for the therapy of these mental health problems. This method of using colors in medical treatments is called chromotherapy or simply‚ color therapy. Chromotherapy is an old concept that uses the visible spectrum (colors) of electromagnetic radiation to promote holistic wellness in an individual (Azeemi & Raza‚ 2005). In this method‚ a therapist locates the source of a particular problem in one’s body caused by the lack of balance in an individual’s energy. He/She

major role in contributing to the reactions which create color. Heat makes electrons in the atoms of the colorant rearrange and become high energy electrons. Also‚ an electromagnetic wave is created through this process. The wavelength of the electromagnetic wave determines what color light will be given off. However‚ electromagnetic waves may take the form of heat‚ ultraviolet rays‚ or light. Certain atoms must be used in order for these waves to create light. Since their discovery in 600 A.D.‚ fireworks

Cohen provides three different spectrums of family change in the text. The idea of change comes in many varieties and is often closely associated with a groups political viewpoint. The spectrum ranges from those who are staunchly opposed to change in any form‚ to the group that believes that change is imperative and must occur at all costs. The poll conducted by the Pew Research Center in 2010‚ indicate a relatively even distribution. However‚ the results seemed to present a pattern based on

Basic Physics Content with Answers 1. In the absence of air resistance‚ a ball of mass m is tossed upward to reach a height of 20 m. At the 10m position‚ half way up‚ the net force on the ball is A. 2mg. B. mg. C. mg/2. D. mg/4. B is correct‚ as a vector diagram would show. Other choices show carelessness or confusion between force and speed‚ and what constant acceleration means. 2. When you drop a ball it accelerates downward at 9.8 m/s2. If you instead throw it downward‚ then its acceleration

considerably. The requirement of the system is that it is to be installed without any cables attached to the sensor nodes. This calls for wireless communication‚ and that for that antennas are needed. A train is a difficult environment to transmit electromagnetic (EM) waves in. It is full of metal and EM-waves cannot pass through a conducting material. Having much metal in its vicinity also affects the function of the antenna. This needs to be taken into consideration when making the design. The constructed
