Also‚ from previous knowledge that I had about how neon lights were formed‚ I imagined that the electrons got excited when they got some sort of voltage or energy‚ and I also knew that when they got relaxed they emitted energy known as photons or light. However‚ this does not explain the colors in a firework. I also did not know that it was possible to use something other than electricity to excite the electrons. To start my experiment‚ I and my group followed these steps. My group put

The Bob Knowlton Case Study Summary Bob Knowlton is the head of the Photon Lab when a new member‚ Simon Fester‚ was introduced to his lab. He begins to feel inferior to his new member and feels that he cannot voice his concerns to his superior‚ Dr. Jerold. After a period of events and insecurities‚ he finds a better position with more salary and takes the job immediately. Dr‚ Jerrold and Fester were shocked by Knowlton’s decision. The lab took a large hit as Fester went on to work on another

semiconductor.‚ which emits light when activated. When a fitting voltage is applied to the leads‚ electrons are able to recombine with electron holes within the device‚ releasing energy in the form of photons. This effect is called electroluminescence‚ and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semi-conductor. An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern. Appearing

the nature of light. Unlike what was proposed in Electromagnetism‚ light and other electromagnetic waves are at the present seen as taking the form of quantized‚ self-propagating oscillatory electromagnetic field disturbances which have been called photons. In 1802 Gian Domenico Romagnosi‚ an Italian legal scholar deflected a magnetic needle by electrostatic charges. Actually‚ no galvanic current existed in the setup and hence no electromagnetism was present. In another paper published Albert Einstein

Photosynthesis and Semi-Conductor based Solar Cells Plants‚ by shear desire to survive have developed the worlds most efficient and reliable power supply by way of photosynthesis. Scientist for years have tried unsuccessfully to duplicate the process of photosynthesis. However‚ for the purpose of this paper‚ I will compare and contrast how energy and electricity is generated through photosynthesis and a semi-conductor based solar cell. In addition‚ this paper will explain how both processes

million degrees Fahrenheit‚ and the density was only 10% of that of water. At this temperature stable atoms were still not able to form. The interactions between electrons and photons continued for 300‚000 years‚ until the universe had cooled to 6000 k (Kelvin)‚ roughly the temperature of the surface of the Sun‚ and the photons were becoming too weak to knock electrons off atoms. Over the next 500‚000 years the background radiation decoupled‚ and had no more significant interaction with matter. The

Higgs boson. In layman’s terms‚ different subatomic particles are responsible for giving matter different properties. One of the most mysterious and important properties is mass. Some particles‚ like protons and neutrons‚ have mass. Others‚ like photons‚ do not. The Higgs boson‚ or “God particle‚” is believed to be the particle which gives mass to matter. The “God particle” nickname grew out of the long‚ drawn-out struggles of physicists to find this elusive piece of the cosmic puzzle. What follows

INTRODUCTION This is a useful circuit for various purposes. In this circuit a counter is activated when a continuously supplied light is been blocked. It uses a counter IC CD 4033.An LDR enhances the counting process. This circuit an be used for various applications such as to count products going over a belt‚ and for counting persons passed at a point etc The project is done as a prototype and its Real one can display a three to ten digit numbers and can count unto thousands.
