Total internal reflection

basic fiber optic will be made of: • An inner cylinder shaped object that consists of a high refraction medium, commonly known as the ‘Core’. Here in the core is where light begins to travel and refract when sending data across. • A middle cylinder that surrounds the inner part of the cable (Cladding). This is one of the layers of materials that have a lower refractive index. By being in contact with the core which has a higher refractive index, the cladding causes light to be confined to the core of the fiber by total internal reflection. This is what will prevent any sort of leaks or loss of transmission data. • The outer protective layer, it is known as the jacket, buffer coating or polyurethane (PVC). The function of fiber optic cables can be explained through the physics of it. When light is transmitted through the Core of the fiber optic, light travels and constantly bounces off from the cladding of the fiber optic. This process is called total internal reflection, this is because the cladding does not absorb the actual light that is traveling through the core, and instead it bounces the light as explain before. This allows the light wave to travel great distances compared to the standard copper wires that are used. Loss of data transmittion in fiber optics is largly due to diffraction, when the light passes through the core, narrow slits or openings within its interior cause fringes of light and huge loss of package data as the light is bent. Another issue that can…

A ray of light travels in a straight line. This is true until it passes from one medium (eg. air) into another medium (eg. glass) of a different optical density. When this happens, the ray of light changes speed causing it to bend either towards or away from the normal which is an imaginary line at 90 to the interface between two mediums. This is called refraction. How much it bends depends on the refractive indices of the two mediums which is a ratio of the speed of light in one medium…

In today’s world sensors especially optical sensors have many emerging applications beginning from the medical diagnostics to detect the pollution in the environment. Because of these wide range of applications the challenges faced to design, proper functioning and maintenance of an optical sensor requires immense knowledge of optical, material, and environmental properties that could affect sensor performance in all aspects. The wavelength range of the laser, interactions between the signal…

Refraction of light is the change in direction of a wave passing from one medium to another caused by its change in speed. This is the bending or breaking that occurs throughout this lab. Learning about refraction is the main purpose of this lab and is explained through four separate experiments. The first experiment includes a medium size glass, water, and a pencil. The first step of this section was to fill the glass to two-thirds full of water. Then take the pencil and circle it around both…

mastery on the assignment in Module 1. Module 1 content was readings from the IRIS website. The content I read related to classroom behavior problems that an educator would encounter and strategies that could be used. After reading the IRIS module I was able to complete the assignment for module 1 with ease. The assignment questions were well written that I was able to complete with the material I had just read from IRIS module. 2. Reflect and discuss how the content in Module 2 prepared you…

Throughout the following essay, I will talk about my reflection on the development of the key skills that I gained during my first academic year that I believe to be the most valuable assets that an entrepreneur needs to accomplish. Moreover, these accomplishments that I acquired during Organisational Behavior and Academic Professional Skills modules have prepared me not only for my next academic years but also in everyday life. During these modules I enhanced my writing skills, time management…

In the article, The Role of Reflection in the Effects of Community Service on Adolescent Development: A Meta-Analysis, researchers van Goethem, et al. explored the benefit reflection has on adolescents participating in community service. The act of reflection is when a person takes mindful approach to thinking the relationship between community service and possible psychological benefits (Ogden & Claus, 2006 as cited in van Goethem, et al., 2014). Reflection is important part in the process of…

human constructs. The pure unadulterated grandeur of nature stretched for miles ahead of me. After what seemed like a blissful eternity I reached for my camera to capture the moment and was immediately struck by an unexpected feeling of guilt as if this small action had disturbed the balance of the universe. In a small way it had. As I look back I realize that a picture is worthless in comparison to the memory that I hold of that moment and the snapshot I took was only a perversion used to…

1. Client: “I was so used to her being there. I needed her but I never told her so. Now that she’s gone, I realize just how much she meant to me” Worker: You feel alone. You are anxious and worried that you will not find someone else. Mr. K’s respond by saying that he is afraid of finding love or even if he happened to be in a relationship he would tell his partner how much she means to him and not hold it in. I think Mr. K will be more opened in expressing his feelings. The two…

first to identify reflection as a specialised form on thinking. He considered reflection to stem from doubt, hesitation or perplexity related to a directly experienced situation. In my opinion I think it is important to take into account that every individual has their own method of reflection;…
