Optical devices. An optical device is any technology that uses light. An optical device can be as simple as a mirror, or as complex as the Hubble Space Telescope.. Microscopes. Hans and Zacharias Jansen of the Netherlands first built a microscope in about 1595.. What is . colour. ?. A sensation caused by light in our eyes. Cones and Rods. What is light?. Particle?. Wave?. Rays. We’ve got our best scientists on it. Light is a particle because…. It has mass and momentum (REALLY SMALL). Geometrical optics. , or . ray optics. , describes light propagation in terms of "rays". The "ray" in geometric optics is an abstraction or "instrument", that can be used to predict the path of light.. Real-time. Rendering of Physically Based Optical Effects in Theory and Practice.

Light leaving the candle travels in all directions, but we only SEE the light that travels in to our Eye-Brain. ANOTHER WAY TO THINK OF . they are: Geometrical optics - this area of optics operates on the primary assumption that light travels in a straight line. Although this is an abstraction of reality, it nevertheless permits rathe The LEOK-1 Optics Experiment Kit is developed for general physics education in universities and colleges It can be used to construct eight experiments covering the basic experiments in geometrical opt What is fiber optics. Fiber optics is simply strands of flexible glass as thin as human hair that is used for telecommunications. .. These strands carry digital signals with . light.. When hundreds or even thousands of these strands are arranged in bundles, it is called an optical cable.. Light = straight path. . absorbs energy as its electrons. move from a low to a high energy level.. An atom:. emits light when an electron moves from a high to a low energy level..  .  .

Reflection off a flat surface follows a simple rule:.
