RADIATION HISTORY Basic Terminology Radiation - A form of energy carried by waves or stream of particles (photons) X-radiation - A high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube High-energy Radiation - A form of radiation that is able to pass through substances (e.g. the human body) X-ray - A beam of energy that has the power to penetrate substances and record image shadows on photographic film Radiology

1. Forward Biased LED- A process when a positive voltage is applied to the p region and a negative voltage to the n region. 2. Incoherent Light- Light in which the electric and magnetic fields of photons are completely random in orientation. Typically emitted from light bulbs and LEDs. 3. Laser-(light amplification by stimulated emission of radiation) used to provide the high-powered‚ tightly controlled light wavelengths necessary for high-speed‚ long-distance optical fiber transmission. 4. Output

Hird1 & Seth J. Putterman1 Relative motion between two contacting surfaces can produce visible light‚ called triboluminescence1. This concentration of diffuse mechanical energy into electromagnetic radiation has previously been observed to extend even to X-ray energies2. Here we report that peeling

Nicoletta Philippides March 15‚ 2013 Mr. Dunleavy‚ Period 4 The Effect of Fossil Fuels on Biodiversity & Alternative Energy Resources Fossil fuels are hydrocarbon deposits derived from the remains of ancient plants and animals under enormous amounts of heat and pressure. Oil‚ or petroleum‚ is one of the most common fossil fuels utilized by people all over the world on a daily basis. Crude oil is a smelly‚ yellow-black‚ viscous liquid composed of mostly nitrogen‚ oxygen‚ and sulfur‚ which is

investigate the size and shape of particles. These range from basic (generally older) techniques such as sieving and use of optical microscopes through to more advanced techniques‚ such as using a coulter counter‚ a scanning electron microscope or photon cross correlation spectroscopy. You will cover a range of techniques in the lectures that accompany this section of the module and you should refer to your lecture notes for further details. The aim of this practical is to examine different techniques

protons and electrons recombine‚ the electrons enter a higher energy level (n=3). Then‚ when the electron drops from the n=3 level to the n=2 level‚ an Hphoton is emitted. 2 This photon has a wavelength of 6563 Å‚ and therefore corresponds to the red portion of the visible spectrum. It is these H photons which give the nebula the distinctive red color which we see. The extreme brightness of the O-type and B-type stars‚ coupled with the Earth’s atmosphere‚ has always made

spectrophotometer measures the amount of light that a solution absorbs. This is done by bombarding the sample with a beam of light of known intensity. Basically‚ this beam is composed of photons that the sample may absorb. As a consequence‚ the pre-assembled light detector in the machine receives less number of photons. The transmittance (T) relates this detected light intensity (P) to the incident one (Po) by the equation T = P / P0 (1) It should be noted that transmittance simply dictates the

Purpose and Hypothesis: Purpose To determine if light intensity affects the rate of growth in Brassica rapa. Hypothesis If the plant that is exposed to high intensity light grows more‚ then plants can adapt to absorb more photons for photosynthesis. Eventually‚ the rate of photosynthesis will top out‚ and stop increasing‚ due to the lack of one of the components necessary for photosynthesis. Background: Photosynthesis is a process used primarily by plants but sometimes by other organisms to
