Physics Education/Light_and_Optics

  • Applications Of Light: Scanners - Tutorial with bibliography.
  • Fraunhofer Lines - Prominent Fraunhofer lines in the spectrum of the sun are shown, together with their corresponding wavelengths. Very pretty!
  • History of Optics - Timeline of optics-related historical moments.
  • How Stuff Works: Light - Seven-segment detailed explanation uses drawings and animations to show how light works and how photons are generated, with many related links.
  • Moiré Phenomenon - A book and a downloadable moire demonstration kit for printing on transparencies.
  • Nanoptics, Inc., Fiberoptic Tutorial - History, theory and use of fiber optics.
  • Oatmeal Box Pinhole Photography - Photo gallery plus directions to make a pinhole camera, take pictures and develop them. Also, links to other pinhole camera sites.
  • Optical Fibres Project - How optical fibers work, and information on reflection, refraction, Snell's Law, total internal reflection and critical angles.
  • Optics Exercises and Tutorial - (Univ of Florida). A sample electronic lecture or worksheet.
  • Optics for Kids - An overview of the basics of optics suitable for elementary school children. Also discusses careers in science and engineering.
  • Polarized Light - Fascinating facts about polarized light, from rainbows to beetles, from viking navigation to LCD displays. Myths and truth about polarized sunglasses. Also a shop with polarized-only items.
  • Reflections In Choppy Water - Why does light reflecting off a lake or ocean appear to be "smeared" into a long strip?.
  • Scanning Electron Microscopy (SEM) - Learn about the scanning electron microscope and its uses.
  • Sighting the First Sense - Introduction to light. Topics touched upon include reflection, refraction, interference and includes interactive applets to demonstrate theories. Designed by students for the ThinkQuest Internet Challenge 2000.
  • The Speed of Light - Describes how the speed of light was measured. Includes curriculum-based science quizzes about light for K-12 (grades 4 to 7) students.
  • Tux Teaches Photonics - A collection of information, lessons and quizes about photonics, taught by Tux.
  • WebTOP - A 3D interactive computer graphics system that instructors can use to help teach optics, and that students can use to simulate and visualize optical phenomena to help them learn about optics.
