  • Cat's Eye Nebula Research Paper

    Huggins studied the spectrum of NGC-6543, he found that the spectrum is dominated by discontinuous lines, emission spectrum, rather than continuous like in the stellar spectrum. The first identified line was the hydrogen Balmer line (H). This discontinuous spectrum confirms Herschel’s idea that the PN gets its energy from a nearby star. Moreover, when Hubble in 1922 found a relation between the magnitude of the central star and the size of the PN, he proposed that the emission spectrum of PN is…

  • William Huggins Research Paper

    build it in London, he would have greatly hindered his chances to make great discoveries such as being one of the few astronomers to discover a new outlet of science, astrophysics. Huggins and his wife also spent time in their observatory observing emission and absorption lines of numerous cosmic objects. When analyzing NGC 6543, also known as the Cat’s Eye Nebula, on 29 August…

  • Homer Simpson's Thermal Radiation?

    by the emission of electromagnetic waves. The waves hold energy away from releasing object. For a normal temperature, the radiation is in the infrared region of the electromagnetic spectrum. The relationship ,conducting the net radiation from a hot object is called,” Stefan Boltzmann Law.”In 1879, it empirically obtained by Josef Stefan. In 1884, it was obtained theoretically…

  • The Ultimate Space Book

    matter from a state of extremely high density and temperature that according to current cosmological theories marked the origin of the universe. 3. This is the red shift the displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance. Stars 1. So creating a brand new element requires loading an atom's…

  • The Importance Of Photoluminescence

    together with the emission of a photon. According to Seitz (2006) found in the Credo referencing database, “Photoluminescence excitation spectra are determined by measuring emission intensity at a fixed wavelength while varying the wavelength of the incident light used to produce the electronically excited species responsible for emission. The excitation spectrum is a measure of the efficiency of electronic excitation as a function of excitation wavelength. Photoluminescence emission…

  • Persuasive Essay: How The Blind See The World

    Persuasive Research Paper How the Blind See the World Jeremy is an eight year old blind boy who has just taken the hearing test provided by the school. The test results were astonishing; Jeremy could hear about 1.2 times better than the average sighted child. Jeremy’s teacher, Mrs. Lundsten, was amazed by her handicapped student’s hearing ability. Like Mrs. Lundsten, people throughout history have thought of blindness as a handicap and that these people can not take care of themselves.…

  • The Pros And Cons Of Regulation Of The Environment

    unsuccessful up to this point as both political parties cannot agree on regulations that suites all parties involved. The United States needs to take responsibility and be the first country to enact a national policy that will significantly reduce emissions because by doing so will show the rest of the world that a big power such as the ourselves are in fear of an environmental disaster then the rest of the world will get encouragement to follow suite. The issues that we face when discussing Cap…

  • Thermo-Insulated Living Physics

    Violet is at the short-wavelength end of the visible spectrum, 400nm, so it reflects the short wavelengths and absorbs longer wavelengths. However, red light is at the long-wavelength end of the visible spectrum, 700nm, so it reflects long wavelengths and absorbs shorter wavelengths. The shorter the wavelengths, the higher the light energy is so the temperature of the colours near the ‘violet’ end of the visible spectrum increases more drastically than the colours near ‘red’ end. Therefore…

  • The Pros And Cons Of Diesel Emissions

    Diesel Emissions The controversy that is surrounding diesel emissions have become a growing concern in many communities and many other organizations including the EPA. The EPA is the Environmental Protection Agency and their job is pretty self-explanatory they are put in place to protect and create laws to prevent and protect the environment from pollution and many other matters. The essential question I am researching is whether or not the black smoke from diesel exhaust is polluting to the…
