Physics Of Light And Light - 1182 Words

Through the fields incorporating the science of light, astronomers use factors such as wavelengths to interpret stars’ temperature, heat, distance, size, mass, density, etc. To obtain all of this information certain light gathering instruments must be used. These instruments include telescopes. To record this information spectrographs are also mainly used to record the spectrum and dispersion of light. In light there are different waves and particles. Light is made up of electric and magnetic fields. Due to this fact, light is an example of electromagnetic radiation, it is the changing of these fields to travel through space shifting energy maneuvering from one area to another. Since light is an electromagnetic wave, each one has a certain wavelength. Telescopes help us to view the visible light of the electromagnetic spectrum. Most of the electromagnetic spectrum, such as infrared, x-rays, ultraviolet, and gamma rays, don’t reach earth’s surface to be examined. A telescope in space, above the atmosphere, however, is said to be diffraction limited. Since the speed of light is constant a wavelength of radiation of a star can be seen as its frequency. Frequency is recorded based on a certain number of waves emitted within a brief second. Optical Telescopes have two types: reflecting and refracting. In 1609, Galileo had developed the first telescope. From here on out, ideas back then of the geocentric solar system were finally put to rest through the use of the firstShow MoreRelatedPhysics Of Physics Regarding Light Rays1581 Words   |  7 PagesI have always been interested in the way light travels, not just in how, but also in all the other factors that affect the light rays, including the speed, the velocity, the distance, as well as others. In my past years of school, I had been able to explore areas of physics concerning light rays, as part of my physics course. However, I had previously only learned the basic principles, such as the laws of refraction and reflection. Because I chose to focus on Chemistry and Biology, I was not givenRead MoreAll About Light-Physics842 Words   |  4 PagesJAENA (SPJ) LIGHT * Light is part of the electromagnetic spectrum, the spectrum is the collection of all waves, which include visible light, Microwaves, radio waves ( AM, FM, SW ), X-Rays, and Gamma Rays. * In the late 1600s, important questions were raised, asking if light is made up of particles, or is it waves .? * Sir Isaac Newton, held the theory that light was made up of tiny particles. In 1678, Dutch physicist, Christian Huygens, believed that light was made up of wavesRead MoreThe Physics Of The Gas Of A Solution And The Amount Of Light That The Solution Absorbs2111 Words   |  9 PagesMultiple scientific concepts were exemplified in this experiment and one particular goal of this lab was to learn more about the Beer-Lambert Law which establishes a linear relationship between the concentration of a solution and the amount of light that the solution absorbs. Moreover, another objective of this experiment was to gain an understanding about the mechanical components of a spectrophotometer and to successfully use the device to measure absorbance or transmittance values. Lastly, anotherRead MorePhysics Experiment : Spectroscopy, Hydrogen, Mercury, Other Gases And Light Sources Using Spectroscopy1037 Words   |  5 Pagespurpose of the experiment: To observe the emission spectra of hydrogen, mercury, other gases and light sources using spectroscopy. (b)The theoretical background: Classical physics theories could not explain why the bright lines at discrete wavelengths appeared, but with the advent of Bohr’s model of atom, it was now possible to explain this phenomenon, which also used the key concepts of classical physics. Bohr’s theory states that an electron can reside in any of the several orbits inside an atomRead MoreProviding the basis of nineteenth century physics, Youngs Double Slit Experiment proved that light500 Words   |  2 PagesProviding the basis of nineteenth century physics, Youngs Double Slit Experiment proved that light was made up of waves. During Thomas Young’s time, it was very difficult to describe the behavior of light. The predominant theory was that light was made up of particles. However, in his experiment, Young was able to observe the interaction of light waves when passed through two slits, showing the wave-like nature of light. This report will cover the reasons for Young’s experiment, the experimen t itselfRead MorePhysics in Cameras713 Words   |  3 Pages The way that cameras are able to do this is through physics. Cameras are relatable to physics because they involve visible light, light refraction, light reflections, and electromagnetic fields in the motor. Cameras are involved with physics because they use visible light to capture a picture. Visible light is part of the electromagnetic spectrum. The electromagnetic spectrum contains different wavelengths and frequencies. The visible light spectrum is the part of the electromagnetic spectrumRead MorePlank, Einstein and Black Body Radiation1400 Words   |  6 Pages19th century physics was mostly thought to be at an apex. One man at the time, William Thomson Kelvin [cited by Glen Elert in The Physics Hypertextbook], said along the lines of â€Å"There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.† This statement was to quickly become fiction with the beginnings of the 1900s. Two major problems in physics were still apparent; Theories on the luminiferous ether. That is the understanding that light is a wave,Read MoreThe History of Physics Essay1534 Words   |  7 PagesThe History of Physics In order to attempt to trace the origins of the modern science that we now refer to as â€Å"physics,† we must begin with the origin of the term itself. Taken from the Greek word â€Å"physika† meaning growth or nature, physics most obviously began as the intelligent study of the human environment (Webster 393). From superstition and religious practices, the foundation of all other sciences was born. These concepts have subsequently grown into what we regardRead MorePavel Alekseyevich Cherenkov and the Cherenkov Effect1078 Words   |  4 PagesThe 1958 Nobel Prize in Physics was awarded to Pavel Alekseyevich Cherenkov, Ilya Frank and Igor Tamm for the discovery and the interpretation of the Cherenkov Effect. Cherenkov radiation is the electromagnetic radiation emitted by particles moving through a medium faster than the speed of light in the same medium. It was fist a detected by Soviet scientist Pavel Alekseyevich Cherenkov, of who the effect is named after and a theory was later developed by Ilya Frank and Igor Tamm. Cherenkov’s contributionsRead MoreEssay on Physics in Everyday Life1684 Words   |  7 PagesPhysics in Everyday Life 1 Just about everything you do from moving to eating to listening to music involves physics. Now that I have really explored them I think it is hard to go about our day and not do something that involves physics. Some of the things I will talk about are getting out of bed, the eye and how eye glasses help a person see better, speakers, the Frisbee, sailing, and the pulleys I use to get my jeep unstuck in the mud when I ride in the woods. All of these
