  • Hdr Photography Research Paper

    SHAH How to do HDR photography (lions) HDR Photography HDR (High Dynamic Range) photography is a form of image processing that uses a series of images captured at different exposures to produce one, amazing photo. The dynamic range is a term used to infer to the ratio of darkness to the light. The idea is usually to compress the compress the light and have it appear on the final processed photo or computer in the same manner the eyes sees it. According to Photography.TutPlus, a good digital…

  • Electromagnetic Waves Vs Mechanical Waves

    Firstly, its advantages include being safe and painless. Unlike X-ray, MRI scanners do not use ionizing radiation; instead they use magnetic fields and radio waves which are harmless and can be absorbed by the body without causing mutations because radio waves have a low frequency and thus a low energy that doesn’t cause harm. Secondly, the pictures that are…

  • The Zeeman Effect Essay

    The experiment is an investigation about the Zeeman Effect in an atomic Cadmium lamp. The part of the spectrum observed will be the 645nm (red) emission line. Electrons occupy energy levels within an atom when a photon of energy hf is absorbed by an electron in the n=1 level and if the energy is such that the electron is excited and ascends to the n=2 level after some time the electron will then descend back to the n=1 level and a photon of hf will then be emitted again. Each atom has its own…

  • Interpretation Of The Noesy: Nuclear Overhauser Effect

    Interpretation of the NOESY: (Nuclear Overhauser Effect) spectrum of 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a) is as follows. Strong coupling interaction of protons of 2nd and 4th position in 1-(2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)azepan-2-one (3a), was not so strongly observed in COSY because it involves long range coupling i.e. protons attached between 2nd and 4th carbon atom. Hence, we studied NOESY to know the spacial interaction between these two protons. Thus, the…

  • Polar Bear Essay

    The polar bear is part of the Ursidae family and it’s scientific name is, Ursus Maritimus. It’s physical characteristics are that it is white, six to nine feet and 800 to 1,300 pounds. It feeds upon seals and fish for nutrients. The polar bear population is decreasing drastically because of global warming and is at an all time low of about 22,000. Even though they live most of their lives in the water, their home is on the ice nursing and taking care of their cubs. They were marked as threatened…

  • Essay On Visual Acuity

    Visual acuity Main article: Visual acuity Visual acuity is the eye's ability to detect fine details and is the quantitative measure of the eye's ability to see an in-focus image at a certain distance. The standard definition of normal visual acuity (20/20 or 6/6 vision) is the ability to resolve a spatial pattern separated by a visual angle of one minute of arc. The terms 20/20 and 6/6 are derived from standardized sized objects that can be seen by a "person of normal vision" at the specified…

  • Visible Light Communication Essay

    rates in wireless communication and to have better performance of networks especially for indoor networks using light emitting diode (LED) lamps [2]. LED, has many benefits such as low power consumption, small size, long life, low cost, low heat radiation. So they are used in numerous applications, like traffic lights, advertisement displays, and indoor lighting equipment and so on. LED based Li-Fi can provide internet connectivity to users instead of using existing wireless technologies…

  • Importance Of Compound Microscope

    Introduction The microscope is an optical instrument that produces large images of small objects that cannot be observed by the human naked eye. There are two types of light microscopes: compound microscope and Electron microscope. Light microscopes are divided into two categories: Compound microscopes and Stereoscope microscopes. Electron microscope functions in the following way; a stream of electrons emitted from an electron source built in the microscope, the obtained image is in black and…

  • The Importance Of Photometry In The Laser Interferometer

    1 Introduction Interferometry is a measurement technique which utilizes the interference of waves in a medium to cre-ate interference patterns [5]. In general, the waves can be light, sound or radio waves. The interference pattern is detected by a photodetector and it provides some useful information about the properties of the object or phenomenon under test. Interferometers are used to make very small measurements that cannot be achieved with any other method. An important…

  • Thermo-Insulated Living Physics

    Introduction Thermodynamics is an essential concept examined during the construction stage of houses, especially in the countries reaching extreme temperatures, such as Australia. By understanding the physics involved in thermodynamics throughout the construction stage of houses, such as heat transfer involving different colours and thicknesses, it is possible to re-examine the insulation of houses in hot countries. Such a report can lead to finding the most appropriate colour and thickness for…
