LIGHT sa COLOR sa ELECTRIC LIGHTING sa ELECTRIC LIGHTING CONTROLLER sa ELECTRIC LIGHTING FIXTURE sa INFRARED sa INTERFEROMETRY sa LIGHT BEAM COMMUNICATION sa LIGHT BOX sa LIGHT DISPLAY sa LIGHT EMITTING DIODE sa LIGHT FILTER sa LIGHT IN DRAWING & PAINTING sa LIGHT METER sa LIGHT PEN sa LIGHT POLLUTION sa OPTICS sa POLARIZED LIGHT sa SPECTROSCOPY sa ULTRAVIOLET xx OPTICS xx PHYSICS How to detect ultraviolet, visible and infrared radiation. Part 1. Experimenting with thermister, thermopile and pyroelectric detectors. How to detect ultraviolet, visible and infrared radiation. Part 2. Photodetectors, photoemissive detectors, etc. Concept of reflectivity of light is discussed. Light sources for electronic projects and instruments. A look at the most common light sources and an in-depth explanation of how LED's are built and operate. Alpha/theta meditation goggles can help you relax. Produces restful alpha waves through a process called photic stimulation. Build this pocket-size photic stimulator that runs on a 9-volt battery. Est. cost: $43. Shedding light on the subject of light. Studying some of the basic properties of light with simple equipment such as a flashlight, small mirrors, a magnifying lens and a pair of eyeglasses. Project Ganymede. How to measure the speed of light by timing the occultation of Jupiter's moon. How to construct a homemade refractometer that requires a helium-neon laser as a light source. Also, a simple apparatus that demonstrates the principle of a refractometer using a protractor, an aquarium, and a beam of light. A refractometer measures the speed of light, indirectly, in various liquids. How to construct an amateur's version of A.A. Michelson's apparatus for measuring the speed of light. How to create and observe a dozen or more higher-order rainbows in a single drop of water. How to set up an apparatus to make the water bead, illuminate it and measure the angles through which the light rays are deflected. Includes a chart of calculated angles of the first twenty rainbows. Lessons in wave interference demonstrated by observing the colors in a soap film. An analysis of caustics, those mathematical curves (patterns) generated when light reaches a surface by refraction or reflection. The amateur scientist. A ball bearing aids in the study of light. It also serves as a kind of "lens". A study of diffraction utilizing laser beams. Experiments with a retroreflector array, a mirror that removes distortion from a light beam. Experiments with color patterns in soap film. Analysis of shadows cast on the bottom of a pool of water. Looks at the impact of refraction, divergence, convergence, etc. What do phonograph records have in common with windshield wipers? An analysis of the 1963 study by J.B. Lott on the reflection of light from an elliptical section of an ellipsoid and other circular arrays. Producing light from a bubble of air. Turn sound into light through a process called "sonoluminescence". Piezoelectric transducers are cemented to a glass flask filled with water and powered by an audio generator and amplifier. Bubbles introduced into the water produce a dim light visible in a darkened room. Astronomical computing. Computer program, written in BASIC, calculates the dispersion of light through a glass prism. The program fits the Hartmann formula to three lines of known wavelength. | |||||||||
