Fiber Optics Assignment Many modern medical materials and equipment work on a principle which is beyond the capacity of human transducers. Comment and discuss the working principles of an endoscope‚ uteroscope or a rectoscope showing the illuminating path‚ the image path‚ transmission path and the liquid transfer or operating instrument ducts‚ showing the position of suitable valves. This will therefore explain how light travels through an optical fibre and show how such

Fiber Optics Fiber Optic Cable Facts "A relatively new technology with vast potential importance‚ fiber optics is the channeled transmission of light through hair-thin glass fibers." [ Less expensive than copper cables [ Raw material is silica sand [ Less expensive to maintain If damaged‚ restoration time is faster (although more users are affected) [ Backbone to the Information Superhighway Information (data and voice) is transmitted through the fiber digitally by the use of high

AIM : To find refractive index of any liquid (water) using a concave mirror. APPARATUS: A concave spherical mirror‚ water‚ an optical needle‚ a clamp stand‚ one meter scale‚ plumb line‚ etc. THEORY: If the tip of object needle 0 be at the centre of curvature C‚ tip of image will exactly coincide with it. (Principle axis is verticle to the plane). When water is filled in concave mirror‚ object needle is again replaced to move to C’ to remove parallax between tips of object needle and its image. A
