LIGHT PEN A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer’s display. It allows the user to point to displayed objects or draw on the screen in a similar way to a touchscreen but with greater positional accuracy. A light pen detects a change of brightness of nearby screen pixels when scanned by cathode ray tube electron beam and communicates the timing of this event to the computer. Since a CRT scans the entire screen one pixel at

The Bingham Light In the small town of Dillon South Carolina was a small community called Bingham. As a child we were told many stories of the Bingham Light. Ghostly haunting stories by many were told about the farmer John Bingham and how he haunted the woods. This is a short story of my experience. According to legend‚ which changes from generation to generation‚ the farmer tried to warn an oncoming train with his lantern of the broken train tracks‚ which resulted in him being decapitated

The prefect atomic family does not truly exist. Ones psychic can be irrevocably altered because of this one flaw. I William Faulkner’s‚ A Rose for Emily‚ He uses an odd chronological order to show there is always a dark cloud in a perfect would. Faulkner also shows through vivid imagery and symbolism that Emily is a prisoner of two worlds‚ the public and private life. This shows how poor Emily is never able to cope fully with either one because she was never shown how. Emily was looked upon in

Of course‚ we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface‚ incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a good example. You can see just how rough it is if you peer at it under a microscope. When light hits paper‚ the waves are reflected in all directions. This is what makes paper so incredibly useful -- you can read

emergency vehicles. Red color is being chosen as the color for the emergency vehicles strobe lights is because of the night vision capability by using this color. It cannot be denied that red color is more easily to be notice if compared to other color. Red color can catch more attention and alert when we saw red because red is signal us about danger. Advantages and Disadvantages White: light is the most effective attention-getting signal‚ containing all visible spectral wavelengths

Purpose: To investigate the behavior of light when it passes from air into an optically denser medium. Prediction / Hypothesis: When the light (incident ray) passes from air into an optically denser medium with an angle of incidence equal to zero‚ there would be no refraction. When the light passes at an angle from air into an optically denser medium‚ the light (incident ray) will immediately change direction and bent towards the normal which has an angle of incidence of 0. Method:
