PC TO PC FIBER OPTIC COMMUNICATION [pic] Submitted By: lex INTRODUCTION DEFINITION The project PC to PC fiber optic communication deals with data transfer from one computer to another. It uses C programming and the serial ports of the PCs. The ports are programmed in C. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via fiber optic cable. The optical transmitter circuit has a LED which is matched as far the cable

Unilateral Optic Neuritis as a Presentation of Neurobrucellosis Introduction: Brucellosis is an infectious disease due to the bacteria Brucella that causes rising and falling fevers‚ sweats‚ weakness‚ headache‚ muscle pain and back pain. Involvement of Central Nervous System causes Neurobrucellosis resulting in serious complications of brucellosis infection like meningitis‚ stroke‚ cranial nerve lesions‚ or mycotic aneurysms. This condition usually requires treatment with antibiotics that cross

occurs when there is an increase in pressure in the intraocular area. A permanent raise in intraocular pressure of 21 mmHg and over would trigger the onset of glaucoma. When this pressure rises‚ it presses on and causes harm to the optic nerve. Any damage to the optic nerve would prevent visual information from being sent to the brain and therefore visual loss occurs. The exact pathophysiology of glaucoma is not fully comprehended but experts believe that the rise in pressure on the retina causes

(a) (i) Draw one ray of light on the diagram to show the light shining from the lamp onto the key. Use a ruler. Put an arrow on the ray to show the direction of the light. 2 marks (ii) There is a patch of light on the wall. This light has been reflected from the key. Draw a reflected ray of light on the diagram. Use a ruler. 2 marks (b) There is a dark shadow on the table beside the

Forced Perspective is a technique that makes object appear further away‚ closer‚ larger or smaller. It is like an optical allusion‚ making people believe they see something that they actually don’t. Forced perspective is used in photography‚ film-making and architecture. It manipulates visual perspective through the use of scaled objects and the correlation between them and the vantage point of the camera. Forced Perspective in film can be made believable when environmental conditions obscure

The Refraction Of Light Through Different Media Mr. Dechene’s SNC2D January 21‚ 2013 Jordyn D. Testable Question: What effects do different mediums have on the angle of light? Hypothesis: If the light goes through different mediums‚ then the light will bend because it is slowing down as it passes through the medium. Equipment: Semicircular plastic dish Polar graph paper Ray box with single slit Water Syrup Experimental Design: A ray box with a single

REFRACTION THROUGH A LENS Lens: Lens is a transparent refracting medium bounded by two curved surface which are generally spherical. Types of lens: Generally there are two types of lens: 1. Convex lens: It is a lens which is thicker at the middle and thinner at the edges. It is also called converging lens as the light rays converges on passing through it at a point. Focal length of convex lens is taken as positive. 2. Concave lens: it is a lens which is thicker at the edges and thinner at the middle

To What Extent does the Sugar Concentration of Water Affects Its Refractive Index? 1. Introduction 1.1 Background Why do object when placed in a bucket of water bend? This is not magic but it is a property of light known as refraction. The bending of light when it travels from one medium to another is known as refraction. Different mediums have different densities and density is defined as the amount of mass per unit volume. The higher the density‚ the higher is the

The ceiling painting in the church of St. Ignazio is one of Andrea Pozzo’s master pieces; painted between 1685-1694. The Apotheosis of St. Ignatius is a manifestation of the principles of the High Roman Baroque‚ which were monumental‚ emotional and dramatic art. The work itself was to be seen as an immortalisation of the Jesuit Order. The centre portrays a brightly lit sphere with the Holy Trinity‚ St. Ignatius and beam of light exuding from Christ. The painting depicts personifications of the four
