wavelength — the distance between the crests of the waves — or its frequency — the number of crests that pass by in a given amount of time.The higher the energy of the radiation‚ the shorter its wavelength and the higher its frequency will be. Blue light‚ for example‚ has a higher energy and therefore a higher frequency and shorter wavelength than red light Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colours

Emission Spectroscopy Lab Introduction: According to the Bohr atomic model‚ electrons orbit the nucleus in fixed paths with specific energies. Each path is therefore often referred to as an “energy level”. Electrons possessing the lowest energy are found in the levels closest to the nucleus. Electrons of higher energy are located in progressively more distant energy levels. If an electron absorbs sufficient energy to bridge the “gap” between energy levels‚ the electron may jump to a higher

DECONSTRUCTING THE CASINO ROYALE TEASER POSTER Who is communicating with whom‚ why and how? “If you don’t change‚ you die. We had to reinvent Bond.” Barbara Broccoli‚ Eon Productions‚ co-producer of the James Bond films (Total Film‚ December 2006) We know from all the pre-release publicity material for Casino Royale that the producers of the latest James Bond film set out to “reboot” the franchise by making a “darker”‚ “edgier”‚ “more realistic” film‚ with a Bond character who is both “more

Eric Warren SIMS 307: Systematic Innovation Homework #4 – Using a Small Set of Operators Consider the following problem formulator diagram. It describes the problem of how an object puncturing the radiator in your car (the thing holding the water for the cooling system) causes the water to run out so it cannot circulate through your engine and remove the heat. This allows the heat to build up and damage your engine. Below are several I-TRIZ operators. Each operator gives you a hint about some

Importance of Physics in the Modern World By PatrickB‚ eHow Contributor Physics is second only to mathematics in the purity of its principles. Physics describes how the natural world works through applied mathematical formulas. It deals with the fundamental forces of the universe and how they interact with matter looking at everything from galaxies and planets to atoms and quarks and everything in between. All other natural sciences stem from physics. Chemistry is essentially applied physics and

Shawn Fiedler Westover Electric Problem MGMT 486 After organizing and looking at the Westover Electric data‚ I found there to be some trends in the data as for causes for the problems when looking at charts I made. After adding up the total defects in the month and organizing them by type there were three specific defects that accounted for 80.97% of the total defects. Going from most to least number of defects by cause‚ 31.17% happened from abraded wire‚ 25.51% from broken leads‚ 24.29% from
