Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

his telescope as a concave telescope‚ because it has a lens with inward curving surfaces. Till 1611 Johannes Kepler switched the concave eyepiece to a convex eyepiece. This allowed the telescope to gain a much larger range of distance. (http://www.antiquetelescopes.org/history.html)It also allowed the projection of images on to a flat white screen. The only problem was that the images were upside down‚ Johannes Kepler added a third convex lens to make the images the right side way. Even though

(refracting) called the “looker” by aligning a concave and a convex lens inside a metal tube. The convex lens refracted light to a specific point on the concave eyepiece making distant objects look magnified. When Galileo heard about the ’looker’‚ he decided to improveupon its design. Galileo called his model the ’telescope’. In his first attempt‚ Galileo built a three-power instrument containing a convex and a concave lens in 1609. He was more successful in further attempts to magnify objects

brain‚ let us see the world. Sensors in the skin respond to touch and allows us to feel. * * * * The seeing eye… Light enters the eye through the clear cornea. It then passes through the pupil and is focused by the lens on the retina. This thin layer covers the back of the eye and contains cells that are sensitive to light. When light hits the cells‚ they send signals to the brain. There‚ the signals are turned into pictures so we can see. Telescope

INTRODUCTION Defects of Hearing •Hearing defects means ear is not working correctly or as well as it should. •It may occur in more than one part of the ear. •1. DEAF-full or partial decrease in the ability to detect or understand sounds. Deaf usually caused by : - Eardrum is torn-cannot function - Ossicle bone fused together-can’t vibrate - Auditory nerve damaged by loud sound - Cochlea damage due to sickness/ drugs •2. Temporary hearing loss-build-up of earwax •3. Presbycusis- hearing loss
