A REPORT ON LASER 1 Techno India College of Technology Megacity‚Rajarhat Kolkata 700156 A Report on LASER TECHNOLOGY By ZAKIR UDDIN AHMAD Student B.Tech 3rd year Applied Electronics and Instrumentation Engineering 2012 2 Abstract The word laser is an acronym that stands for "light amplification by stimulated emission of radiation." In a fairly unsophisticated sense‚ a laser is nothing more than a special flashlight. Energy goes in‚ usually in the form of electricity‚ and light comes out

troChapter 1: Charting the Heavens (Astronomy Today) SUMMARY The universe is the totality of all space‚ time‚ matter‚ and energy. Astronomy is the study of the universe. A widely used unit of distance in astronomy is the light year‚ the distance traveled by a beam of light in one year. Early observers grouped the thousands of stars visible to the naked eye into patterns called constellations. These patterns have no physical significance‚ although they are a very useful means of labeling regions

discovered small black crystals of SiC in an electrically heated melt of carbon and alumina (1). The subsequent refinement of this technique (the so-called Acheson process) led to the commercial production of large volumes of small SiC crystals (ground into powder form) for use as an industrial abrasive (2). The commercial product‚ which is made in an electric furnace‚ is usually obtained as an aggregate of iridescent crystals. The iridescence is Kirk-Othmer Encyclopedia of Chemical Technology. Copyright

3.1 CATHODE RAYS 3.1.1 Explain that cathode ray tubes allowed the manipulation of a stream of charged particles. DEFINITTIONS: * Cathode Ray Tube: is an evacuated tube which allows the unobstructed movement of cathode rays from a cathode to an anode. * Cathode Ray: Are negatively charged particles and can therefore be deflected. * This can be shown by 3 facts: * They leave –ve charge on the surfaces they strike * They are deflected by magnetic fields as predicted

Washington State University | Rosalind Elsie Franklin | A story that needs to be told | | 2/3/2013 | Biology 499 * Introduction Have you ever asked yourself‚ exactly what is DNA and why is it so important? DNA stands for Deoxyribonucleic Acid and is found in every living thing. We inherit DNA from our parents‚ half from our mothers and half from our fathers. DNA is made up of sugars‚ bases‚ and phosphates and comes in the structure of a double helix which looks like a spiral

galaxies‚ and evidence that most galaxies have black holes in their centre. The Hubble Telescope is in orbit about 380 miles above the Earth. It views the galaxy without having to look through the Earth’s atmosphere which bends light because of diffraction; also because the atmosphere is moving. This is why stars appear to twinkle and blurs the image seen from telescopes on Earth. Because the Hubble Telescope is above the Atmosphere‚ it produces much finer images. The Hubble Telescope can also observe

Be sure the loop is clean for the next sample (no more flame color). 5. Option: Watch the flame through a diffraction grading slide to see the bright line emission spectrum. Conclusion: In conclusion‚ we discovered that every metal ion solution has a distinct emission spectrum. Low energy red was proven to be on the low energy side. While violet indicates
