Providers Many of the fastest Internet plans come from fiber-optic networks. Fiber-optic Internet, especially Fiber to the Home (FTTH), delivers consistent broadband access. It’s a technology many providers have turned to for the crux of their networks. Fiber provides network reliability and speed potential. Fiber-optic Internet introduced the first gigabit speeds for residential use. Hair-thin, flexible glass strands make up a fiber-optic network. Cables of these strands make up a delivery method

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

Unit D Summary: Light and Geometric Optics 10.1:Light and The Electromagnetic Spectrum Chapter 10.1 covers light and the electromagnetic spectrum. This chapter starts off by describing how light is a form of energy that travels in waves. The properties of said waves include a crest (the highest point of the wave), the trough (the lowest point of the wave), and the rest position (the level of a wave without energy). The three most important properties of a wave are the wavelength, the amplitude

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

Photography’s “mysterious” beginnings and growth due to social desires were the first instances in which it could be seen that the way people say the world around them would completely change. The human desire to continue to find a better type of production lead to the ability to mass produce images and therefore allowed for information to be spread nationally as well as international. Photography allowed people to see places they had never seen, they were able to help support scientific discoveries

"Taking pictures has become a big part of my life. It is more than a job to me. I find it so crazy because it seems like taking pictures has actually saved me from doing a lot of things that I feared would harm me. With all that I have been through, some of the pictures I have taken have been keeping me sane....they're like memories stuffed in a flat rectangle. I love what I do!” Raetilliah Hayes once stated (Hayes). What is a photographer? A photographer is someone who takes pictures, typically

How can different light sources affect the observations you can make? Different light sources show totally different forms of visible light. From the camera obscura, we could see fuzzy images with single black colors. If the sunlight were not bright enough, the image would be fuzzier. From the prism, we could see refracted spectrum of colors with clearly different wavelengths. From the spectroscope, we could the see different clearer clusters of spectra from various sources of light and elements

Microscope Type Electron (Transmission Electron Microscope AKA TEM) Light (Optical Microscope) Cell Components Seen Organelles, through to the point of being able to observe inside the nucleus Smallest observable organelle, ribosome. Cell structure Smallest visible Organelle, mitochondrion. Specimen Preparation Specimen is stained with materials such as lead, osmium and uranium salts. The salts are then absorbed by the organelles and cell membrane, but not the cytoplasm. This means that the electrons

Would you push the button? In Richard Matheson’s short story “Button, Button”, I think Richard showed the dialogue that was going on between Arthur and Norma to show Norma’s motivations to push the button, to build a unhappy mood between Arthur and Norma, and to introduce Norma. If Richard didn't show the dialogue between Arthur and Norma, we wouldn't know why Norma wanted to push the button, we wouldn't know how Arthur felt about Norma wanting to push the button, and we wouldn't know that Norma

BS1003 – Organic Chemistry Practical 1 Laboratory Report Name: Tristan Chan Yew Kit, U1640436J (T8) Effects of Dichloromethane(DCM) in Extraction of Caffeine from Tea Leaves Purpose To investigate the ability for Dichloromethane(DCM), a moderately polar organic solvent, to extract aqueous caffeine molecules, originating from Tea Leaves suspended in water. Introduction Caffeine, defined chemically as 1,3,7-trimethylxanthine (C8H10N4O2), is an alkaloid that can be found in tea leaves, coffee and many

20th Century At the turn of the 19th/20th centuries Louis Pasteur invented pasteurization while Robert Koch discovered his famous or infamous postulates: the anthrax bacillus, the tuberculosis bacillus and the cholera vibrio. Phase Contrast MicroscopeUV and Phase: By 1900, the theoretic limit of resolution for visible light microscopes (2000 angstroms) had been reached. In 1904, Zeiss overcame this limitation with the introduction the first commercial UV microscope with resolution twice that of

In the image above, we are able to see that the artist has used several different depth cues to create an illusion of depth to those who view it. The depth cues that the artist of this picture has utilized are relative size, occlusion, and texture gradient, which all happen to be specifically monocular depth cues, otherwise known as depth cues that only require one eye to be seen. The monocular depth cue of relative size is used in this image in several areas, both with the people in the image

In this clever ad for Glassex window cleaner, a magician is depicted “levitating” a woman. However, it is alluded to that the woman is actually laying on a glass case, unseen due to the cleanness of the surface. In terms of line, the lines are commonly sharp and long, with the curved lines reserved for only the two figures in the ad. The floor and the curtains employ long, unstopped lines, while the magician and the woman’s lines are much more organic in relation to each other. This also causes the

Anatomy and physiology Assignment 1 of 3 Cell ultrastructure Light and Electron microscope uses light and electron microscopes are both used to see objects which cannot be seen with the naked eye, however the electron microscope has far more magnification levels; 0.2nm magnification 250,000 times, these allow you to see the ultrastructure of cell (Reid, 2017). A light microscope is an instrument that uses visible light and magnifying lenses to examine small objects not visible to the naked eye

The new technology of perspective further enhances the realism of the painting. Perspective makes a realistic style of painting has made great progress. Perspective as one of the most significant achievement of the Renaissance, and still play its great influence, especially make great contributions on the spatial structure(Gombrich 1950). The view was so realistic which not difference between the painted scene and how the actual building’s appears in three-dimensional space. However, this has realistic

6. Problems and Limitations: Immunofluorescence is one of the main methods regarding imaging techniques due to its high specificity and it’s relatively simply implementation. Nevertheless there are also some problems when dealing with immunofluorescence. 6.1. Photobleaching Fluorochromes can lose the ability to fluoresce due to the photochemical destruction of a fluorophore. This phenomenon is called photobleaching [15]. Although this process is not fully understood yet, there are some hypotheses
