Different Energy Levels Of Hydrogen
390 wordsWild Bill's Wild Bohr Quiz Niels Bohr's model of the hydrogen atom, was the primary reason for the understanding of energy levels. Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form of light. He figured the light rays to be quantized, meanin...

Atoms Into An Excited State
285 wordsThe Laser / Atom Connection A laser is a device that controls the way that energized atoms release photons. Laser is an acronym for Light Amplification by Stimulated Emission of Radiation, which describes very succinctly how a laser works! Although there are many types of lasers, all have certain essential features. In a laser, the lasing medium is "pumped" to get the atoms into an excited state. Typically, very intense flashes of light or electrical discharges pump the lasing medium and create ...

Activity Level Of The Athlete
648 words- THE CAUSES OF DELAYED MENARCHE IN FEMALE ATHLETES - INTRODUCTION Greater emphases on the benefits of exercise have led to a greater participation of women in sport at all levels. Exercise has been promoted, endorsed and encouraged in the medical community as a way to reduce stress and maintain a healthy lifestyle. While moderate exercise does provide valuable benefits, intensive exercise associated with elite female athletes poses serious health risks to the female body. The female reproductiv...

Web Problem Of Continuum Versus Discreteness
2,114 wordsweb problem of continuum versus discreteness seems to be related to the issue of infinity and finiteness. The number of points in a line served as the logical floodgate which led to the development of Set Theory by Cantor at the end of the 19th century. It took almost another century to demonstrate the problematic nature of some of Cantor's thinking (Cohen completed Godel's work in 1963). But continuity can be finite and the connection is, most times, misleading rather than illuminating. Intuiti...

Growth In Energy Intensity In Industrialized Countries
599 wordsThe environmentalist view of the energy intensity is based on the legacy of the I = PAT equation in which environmental Impact equals Population, multiplied by Affluence, and further multiplied by Technology (Earth Report 2000: Revisiting the True State of the Planet. 1999). The further desegregation of this formula implies that energy intensity can be looked upon as an integrative variable describing the impact of both technology and affluence. Bruce et al. (1996) argue that intensity is invers...

10 Energy And The Killer Whale
361 wordsEcology Homework 1 a. Producers do not fit because producers take in energy from their surroudings and store it in complex molecules. All other organisms are called consumers. They obtain their energy by consuming other organisms. 6. Producers take in energy from their surroudings and store it in complex molecules while consumers obtain their energy from consuming other organisms and giving off that energy through their bones, phesis, skin, etc. An example of a producer is: All plants, some bact...

Electrons In The Conduction Band
2,490 wordsWhat is a semiconductor and what is the basis of this classification? A semiconductor is a material that intermediates between a conductor and an insulator. Electrical conduction represents the ability of a material to conduct electric charges. Some materials are very good at it and are called conductors; the materials that are hopeless at it are called insulators. Semiconductors (aka semi-insulators) are not very good at it. But under certain conditions, they can almost be a conductor. What are...
