Blackbody Radiation Lab 11 Go to http://phet.colorado.edu/simulations/sims.php?sim=Blackbody_Spectrum and click on Run Now. 1) In this lab‚ you will use the Blackbody Spectrum Simulation to investigate how the spectrum of electromagnetic radiation emitted by objects is affected by the object’s temperature. In this simulation‚ you can input the temperature and observe the spectrum of the radiation emitted. a) The temperature of stars in the universe varies with the type of star and the age

Case-Study Guidant 1.How attractive is the radiation therapy opportunity for Guidant? First we will determine the size of the market and its growth potential. Then we will assess the attractiveness of the market for radiation therapy in general using the concept of Porter’s 5 forces. Furthermore we will connect this information with Guidant’s specifics and its complementary assets to find out if this specific market is attractive for the company. Market size and growth potential The market’s

A patient may receive radiation therapy before‚ during‚ or after surgery. Some patients may receive radiation therapy alone‚ without surgery or other treatments. Some patients may receive radiation therapy and chemotherapy at the same time. The timing of radiation therapy depends on the type of cancer being treated and the goal of treatment (cure or palliation). Radiation therapy given before surgery is called pre-operative or neoadjuvant radiation. Neoadjuvant radiation may be given to shrink a

EFFECTS OF RADIATION Background Radiation is all around us. It is naturally present in our environment and has been since the birth of this planet. Consequently‚ life has evolved in an environment which has significant levels of ionizing radiation. It comes from outer space (cosmic)‚ the ground (terrestrial)‚ and even from within our own bodies. It is present in the air we breathe‚ the food we eat‚ the water we drink‚ and in the construction materials used to build our homes. Certain foods

cellular structure. Ionizing radiation causes atoms and molecules to become ionized or excited. These excitations and ionizations can: * Produce free radicals. * Break chemical bonds. * Produce new chemical bonds and cross-linkage between macromolecules. * Damage molecules that regulate vital cell processes (e.g. DNA‚ RNA‚ proteins). The cell can repair certain levels of cell damage. At low doses‚ such as that received every day from background radiation‚ cellular damage is rapidly

Mrs. Pilar M. Macabinguil ENGLISH IV Teacher MPCHS Madam: In partial fulfillment of the requirement in ENGLISH IV‚ I hereby present to you my term paper entitled “What is Radiation?” This term paper presents a research study on the importance about radiation and how it affects the whole world. In doing a research paper is a big task that must be given more efforts‚ time and patient. It will not be built without references. I always think of doing this not for the

Blackbody radiation is the electro-magnetic radiation emerging from a small hole in a perfectly black box containing electromagnetic radiation at a high temperature. Scientists were interested in setting standards for the electric and thus measured the distribution of the total electromagnetic energy in a black box among the different wavelengths of the light. But not until Max Planck‚ at the turn of the century‚ was a single mathematical formula for the observed distribution of the energy among

The Effects of Radiation on Cancer There are both negative and positive effects of radiation on cancer. Scientists have discovered that radiation can lessen or increase the chance of obtaining cancer. Radio therapy is a treatment for cancer in which X-rays employ controlled exposure to radiation. Radiation also can save lives. The negative effects on humans are that if over exposed to it‚ it can cause migraines‚ seizures‚ and ultimately‚ death. Firstly‚ external beam radiation therapy used on

Radiation pattern From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search Antenna radiation patterns In the field of antenna design the term ’radiation pattern ’ most commonly refers to the directional (angular) dependence of radiation from the antenna or other source (synonyms: antenna pattern‚ far-field pattern).[1][2][3] Particularly in the fields of fiber optics‚ lasers‚ and integrated optics‚ the term radiation pattern‚ or near-field radiation pattern‚ may also be used as
