Unit 7 Assignment 1: Reflection, Refraction, and Optics
On this assignment, I will explain reflection, refraction, and Optics.
Refraction is the change in direction of a wave due to a change in its transmission medium. This is most commonly observed when a wave passes from one medium to another at any angle other than 90° or 0°. Refraction of light is the most commonly observed phenomenon, but any type of wave can refract when it interacts with a medium, for example when sound waves pass from one medium into another or when water waves move into water of a different depth. One real example is when you stick your hand in a pond or a lake, and it looks as if your forearm has been bent.
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. In computer science, reflection is the ability of a computer program to examine and modify the structure and behavior of the program at runtime. Reflection also occurs at the surface of transparent media, such as water or glass.
An optical fiber is a flexible, transparent fiber made of extruded glass or plastic, slightly thicker than a human hair. It can function as a waveguide, to transmit light between the two ends of the fiber. The degragation of signal strength can be caused by light scattering, molecular level irregularities in the glass structure, and UV-Vis-IR absorption.

A good example of refraction of light and reflection of light is a rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors. This angle is a fixed measurement between your eye and the sun. What color is refracted depends upon the critical angle, which is the angle the sunlight strikes the back of the rain droplet. Red light bends the least while violet light bends the most all the other colors bend at an angle that is between the two. Each rain droplet reflects all colors at a given point and time, but only one color comes back to your eye, requiring millions of rain droplets to create a rainbow. As the rain droplets fall…

Fibre-optic telecommunications is simply a method of transmitting information from one place to another extremely fast. This is done by shooting pulses of light through an optical fibre. Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal. An optic-fibre is a small fibre no thicker than a human hair, either made of glass or plastic that is transparent and flexible. The light inside the fibre-optic cable forms an electromagnetic carrier wave that is modulated to carry information. Fibre-optic telecommunications offers the longest and highest bandwidth (data transfer) of any other form of communication. The availability of fibre-optic technology has replaced a lot of the copper wire communications in core networks in developed countries. The modern day Fibre-optic cable was first developed by Gerhard Bernsee of Schott Glass in Germany in 1973. After this in the early 90’s a development of the photonic crystal-fibre these are much better because they have much higher power than the early glass fibre and also their wavelength-dependent can be manipulated to provide better performance. These were first available in 2000 and with this technology the first Fibre-Optic Telecommunications System was developed. Fibre optic telecommunications have three main uses the internet; optic fibres allow for an extremely fast bandwidth this is normally used by big companies and the government, digital television; optic fibre allows for a perfect quality at all times that never cuts out which is crystal clear and never cuts out, and finally telephones; Once again used for perfect quality between long distances it was the original use for fibre optic telecommunication. ‘The glass in optical fibres is…
