Efficient and effective policies to solving climate change Global warming is an issue that has recently been pushed to the forefront of political leaders debates and policy making. With temperatures at the end of the century that ‘might be up by anything from 1.1C to 6.4C’(Economist 2009) and the fact that ‘current average global temperatures are only 5C warmer than the last ice age’ (Economist 2009) there is some serious concern about the welfare of humans over the next century. However the predicament

Lab #4 Emission Spectroscopy and Flame Test Date of Lab: 10/24/13 OBJECTIVE To observe a continuous spectrum‚ emission spectrum‚ and an absorption spectrum‚ and be able to distinguish among the three. To be able to identify metal ions by doing a flame test and looking at a spectrum. At the same time increasing the ability to use and understanding of lab equipment‚ in this case‚ a spectroscope. To be able to calculate the frequency and energy of certain frequencies of light. PROCEDURE

¦Ë = 410.2 nm‚ ¦Ä‚ color emitted: violet Although physicists were aware of atomic emissions before 1885‚ they lacked a tool to accurately predict where the spectral lines should appear. The Balmer equation predicts the four visible absorption/emission lines of hydrogen with high accuracy. Balmer’s equation led physicists to find the Lyman‚ Paschen‚ and Brackett series which predicted other absorption/emission lines found outside the visible spectrum. The familiar red H-alpha line of hydrogen

nebulae‚ emission nebulae‚ reflection nebulae‚ dark nebulae‚ and supernova remnants. A planetary nebula is a shell of gas that is made by a star as its life draws close to an end. These nebulas really have nothing to do with planets. They were given the name planetary nebula because they often look like planets due to their round shell like shape. The outer shell I illuminated by the remains of the star that it came from. Emission nebulae’s are clouds of high temperature gas. Inside emission nebulae’s

seems to be realizing that the old ‘growth at all costs’ model that has previously been followed threatens not only the country’s energy security‚ but its very survival. A green development pathway based on low energy consumption and low carbon emissions is essential if China is to find a sustainable path to growth. The environmental aspects of the plan are likely to be boiled down to five

carbon etc. Since 19th century’s industrial revolution till today emission of Green House Gases into the environment has increased tremendously due to the impact of intense industrialization. Currently it is the biggest challenge to all the effect on the environment. One of the solution for this problem is trading of carbon credits both within and outside the regulated areas. Under this system‚ certain norms regarding emission of Green House Gases are implemented on various commercial units

fossil fuels like coal‚ oil‚ and natural gas combined with fast deforestation has led to unprecedented level of green house gas emission. Here came in to existence the concept of Carbon Emission Trading developed during the Kyoto Protocol in 1997. The Kyoto Protocol sets limits on total emissions by world’s developed economies. The protocol allows countries that have emission units to spare‚ to sell this excess capacity to countries that are over their targets. This research paper discusses what is

optical communication and laser physics. There are several different physical mechanisms that can be used to amplify a light signal‚ which correspond to the major types of optical amplifiers. In doped fiber amplifiers and bulk lasers‚ stimulated emission in the amplifier’s gain medium causes amplification of incoming light. In semiconductor optical amplfiers (SOAs)‚ electron-hole recombination occurs. In Raman amplifiers‚ Raman scattering of incoming light with phonons in the lattice of the gain
