The Effect Of A Light Ray Reflecting - 962 Words

This lab is made up of four different parts. In the first part we will examine the effects of a light ray reflecting at different angles of incident from a convex, flat, and convex mirror. In the second part a light ray will be refracted through a rhombus prism at different angles of incidence. We will measure the angles using a protractor. For the third experiment we will examine the indices of colors as light is refracted through the rhombus. Lastly, we will use polar lens to examine Brewster’s angle and polarization. THEORY PART A: REFLECTION When a light ray hits a point on a plane mirror surface (called the incidence ray), it bounces off that same point and thus changes the course in which it is traveling. An angle of incidence can be obtained by measuring the angle between the ray of incidence and a line normal to the surface of the mirror. The angle of the reflected ray can also be obtained in the same way by measuring the angle between the reflected ray and the line normal to the surface. Measuring the two angles we can see that they are the same angle thus confirming the law of reflection: ÃŽËœr=ÃŽËœi. Eq.1 PART B: REFRACTION Refraction is caused when a ray of light travels through different mediums. When the light crosses through the material it causes the light to bend or refract because the wave does not enter the medium atShow MoreRelatedComparison Between Optical Telescope Systems And Modern Day Times1566 Words   |  7 Pagesreport will be reflecting, refracting and cassegrain which is a combination of both and how different types of error such as aberration effect the telescopes ability to capture an image and the quality of the image it produces. Reflecting telescopes use mirrors to reflect incoming light rays onto a secondary mirror which magnifies it through an eye piece to form an image. (BBC, 2015) When light rays come in contact with the mirror they are called the incident ray and then when the ray reflects backRead MorePhysics Of Light And Light1182 Words   |  5 Pagesscience 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 exampleRead MoreDescription Of The Light ( Thermal Energy )1383 Words   |  6 Pagesmethod whereby the light (thermal energy) is directed back upon the can of water from several different directions, increasing the efficiency. Considering that the reflecting of light cannot add nor remove power, the aluminium does not act to amplify. However, reproducing the rays using a mirror system replicates the power. Each individual ray mirrors the power of the original Sun’s rays, but because there are multiple, a much stronger power source is gained. In addition to this, the rays are targetedRead MoreThe Ozone Layer And Increasing Levels Of Ultraviolet Radiation938 Words   |  4 Pageswithin contemporary society. Unfortunately, UV rays increase the risk of obtaining skin cancer since they permanently alter the DNA structure within our cells, creating a vast array of mutated cells. Research has shown that melanoma is considered the most serious type of skin cancer due to the development of dark spots on the skin, which develop in basal cells at the base of the epidermis caused by the exposure of ultraviolet rays. This problem with UV rays and its high level of skin cancer could beRead MoreThe Burning Of Petroleum Based Fuels1154 Words   |  5 PagesCan you see the light? As the burning of petroleum-based fuels, natural gases, and coal continues, smog will continue to cover the sky. Pollution from said burning occurs as greenhouse gases and chemicals. Specifically, petroleum-based fuels, natural gases, and coal release energy when heat breaks the bonds between hydrogens and carbons, generating energy and releasing carbon dioxide and water as byproducts. This energy often originates from stored energy preserved in organisms that eventually diedRead MoreHistory of the Telescope2127 Words   |  9 Pageswhich collects light, howeve r there are other kinds of telescopes which collect UV and X -Rays. Optical telescopes use lenses to redirect light to a specified point. Different lenses are used for different magnifications of celestial objects. This essay will be mainly discussing optical telescopes. As we go through the history of optical telescope we can see that there are a few concepts that are fundamental to all the different types of optical telescopes, from the reflecting to the refractingRead MoreAnimal Physiology And Anatomy : The Skin Structure Of Panther Chameleons1216 Words   |  5 Pagesdisproving the so thought idea of chameleons being able to change color the same way mollusks do. Instead, with the use of in-vivo spectroscopy, they were able to conclude that chameleons possess minuscule light reflecting guanine structures called iridophores, similar to the light reflecting particles found in fish scales. In fact, by performing a histological transmission electron spectroscopy test, it was clear that two distinct layers of these iridophores were present within the chameleons’ skin:Read MoreThe Theory Of Light And Its Effects On The Human Eyes963 Words   |  4 PagesLight, a concept that has been worked with for many years dating back to 500 B.C. Pyt hagoras hypothesized that humans perceive light due to the human eyes ability to emit rays upon the environment and the emittance gives a human his or her sight (Sekuler). Afterward, human intellectuals started making it more concise to present day knowledge of light. This development of light came from two intellectuals named Christian Huygens and Isaac Newton. Newton exclaimed during the 1700s that light was aRead MoreThe Evolution of Photography Essay1077 Words   |  5 Pagesafter he took the same picture three times, using a different color ribbon. He then combined all three photos together and got one, colored photograph; however, these cameras were bulky and a pain to transport. In 1888, George Eastman made the first light and portable camera under the company name Kodak (Graham 28). These cameras gave people the ability to take a photo almost anywhere. The cameras had to be sent back to the factory so the photographs could be printed. Twenty years after Kodak’s first Read MoreThe Effects Of Light Pollution On Humans And The World1307 Words   |  6 Pagesmisdirected, or obtrusive light that is just as large of an issue. This variety of pollution is called light pollution or photo pollution. The effects of light pollution on humans and the world’s various ecosystems are various and need to be realized. Since their initial creation, light bulbs have continuously grown in number and type. Streets are now lined with bright yellow fluorescent, runways are now mapped out with multi-colored bulbs, etc. The utilization of light bulbs has expanded to
