    Student’s Name Institution Course Name Professor’s Name Date of Submission Optics: Reflection and Refraction and Lab Report Introduction The objective of this experiment was to analyze the laws of reflection and refraction. In this experiment, the relationship between the angle of reflection, the angle of refraction, and the angle of incidence was established. If a line is normal to the surface at the point where the light beam strikes the surface, then the reflected angle is equal to the angle

    The eye is the organ of vision, it is sensitive to light, and each eye is housed in an orbit that is a cavity in the skeleton of the face. It is a spherical structure about 2.4 cm in diameter. [1][2] The wall of the eyeball is composed of three layers of concentric tissues. a. The device layer is a protective cover layer called sclera, consists of two elements [3, 4]:  Sclera covers about five-sixths of the surface of the eye.  The cornea, the peripheral layer consists of a sort of bulge-shaped

  • Fundus Camera Reticle Analysis

    1811 Words  | 8 Pages

    Fundus Camera Reticle Setup (Mydriatic) An often overlooked and critical step in obtaining sharp images is to set your reticle. The reticle is the adjustable viewfinder crosshairs and is unique to each operator’s eye visual acuity. To adjust, place a white piece of paper in front of the camera (alternatively, you can use the camera lens cap on), raise the illumination light to highest and while looking through the viewfinder, turn the eyepiece clockwise and counter-clockwise until crosshairs are

  • Role Of Refracting Telescopes

    996 Words  | 4 Pages

    REFRACTING TELESCOPES What is a Refracting telescope? The role of a refracting telescope is to magnify objects, This is done by refracting the light rays it receives to create a image that is inverted and magnified. When it comes to refracting telescopes there are quite a few different types of refractor telescopes, some examples are are the astronomical telescope, however, they consist of similar Components and parts. Refractor telescopes always have 2 lenses, these are the objective lens,

  • Short Essay On Holography

    4166 Words  | 17 Pages

    hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics. The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interference pattern of seemingly random variations in the opacity, density, or surface profile

    Production process. The manufacturing of spectacles involves the production of lenses as well as frames. Production Process of Lenses: There are different machines used for making lenses. These machines are very expensive. In US dollars their prices range from $500 upto $7000. Lenses are manufactured in four basic parts: 1. Casting-lenses are produced from raw chemicals using a chemical process. 2. Moulding-lens material is reshaped by pressure and heat into the finished or semi-finished lens

    image onto a fluorescent viewing screen coated with a phosphor or scintillator material such as zinc sulfide. Alternatively, the image can be photographically recorded by exposing a photographic film or plate directly to the electron beam or a fibre optic light-guide to the sensor of a CCD (charge-coupled device) camera. The image detected by the CCD may be displayed on a computer. Resolution of the TEM is limited primarily by spherical aberration, but new generations of aberration correctors have been

    4.8.1 Total Fatty Matter After 2 weeks of curing stage, measurement of total fatty matter was done by dissolving 10 g of final product of soybean waste based formulations in 150 mL of distilled water. The mixture were heated and stirred to obtained complete homogenous mixture. 20 mL of 15% H2SO4 was added while heating until clear solution was obtained. Fatty acids on surface of the resulting solution was solidified by adding 7 g of bees wax and reheated. The heating was continued until the waxes

  • Refraction Lab Report

    1923 Words  | 8 Pages

    Refraction: Refraction occurs when light enters a more or less optically dense medium, which therefore has a different refractive index (measure of the velocity light can travel at in the medium compared to in a vacuum in which it can travel at 2.9 x 108ms-1). This causes the light’s speed to increase or decrease, which results in the rays bending towards or away from the normal, so the position of the image formed is dependent on the refractive indices of the two media. For refraction to occur

  • The Importance Of Microscopy

    1211 Words  | 5 Pages

    1. Microscopy The discipline of science which involves magnifying objects which cannot be seen with the naked eye is known as microscopy. 2. Fluorescence- an introduction Certain substances, when irradiated with light (UV, blue or green) emit radiations of their own, whose wavelength is longer than that of the exiting light. This process is called luminescence. There are two types of luminescence: If the excited radiation persists only so long as the exciting light acts on the sample then it is

  • Radar Cross Section Report

    861 Words  | 4 Pages

    Radar cross section (RCS) or echo area or effective area is the measure of target’s ability to reflect radar signals in the direction of the radar receiver i.e. it is the measure of the ratio of the backscattered power per steradian in the direction of the radar to the power density that is intercepted by the target [1]. RCS is a measure of how detectable an object is with the radar. The IEEE dictionary of electrical and electronics terms[1]defines RCS as a measure of reflective strength of a

  • Global Illumination

    1285 Words  | 6 Pages

    Comparison of Local and Global Illumination in Illumination Models Illumination models represent a higher level of computer graphics that calculate how light and shadow effects should be calculated and presented in an image. Lighting is crucial for any sort of image not to exist in a vacuum and instead be part of a scene. Light must come from a clear source, create shadows and reflect on the surfaces of the objects in the scene properly, with different kinds of surfaces reacting differently to light

  • Transmission Electron Microscope Lab Report

    In Transmission Electron Microscope, the electron beam is confined by the two condenser lenses which also control the brightness of the beam, passes the condenser aperture and “hits” the sample surface as shown in the Fig 3.5. The electrons that are elastically scattered consisted of the transmitted beams, which pass through the objective lens. The objective lens forms the image display. The apertures, the objective and selected area aperture are used to choose of the elastically scattered electrons

  • Light Refraction Conclusion

    1110 Words  | 5 Pages

    We are only able to see due to the fact that light from an object travels from the said object and into our eyes.When a ray of light passes through different mediums, it changes both the velocity of the light ray and the direction.This is called the refraction of light rays. This is due to the fact that different substances have different optical densities. The light will travel slower through a substance that is very optically dense and faster through one that is less dense. The refraction of a

  • Reflection Of Light: The Refraction Of Light Waves

    835 Words  | 4 Pages

    What is Refraction? Refraction is the bending behavior of light when it passes through one medium to another. Especially when light travels from an optical dense medium to an optical less dense medium. The refraction of light relates to the change in the direction of which light travels which will then affect the change in the speed of light. When light changes the direction it travels, there will be a change in the wavelength; this change will then lead to the change in the speed of light. When

  • The Importance Of A Light Microscope

    729 Words  | 3 Pages

    A light microscope (LM) is an instrument that uses visible light and magnifying lenses to verify small objects that are not visible to the naked eyes or in finer detail than the naked eye allows. A light microscope uses two or more lenses to magnify the specimen and it have two sets of lenses which is stage and ocular (Bregman, 1983). Specimens are magnified by the objective lens which is magnified 100 times. The specimen is illuminated by visible light from the light source (the illuminator) that
