Lidar - LIght Detection And Ranging.\n\nThis technology is basically using light (usually from a laser) to measure distance.  Common applications are in laser (not ultrasonic) tape measures, surveying equipment, and LIDAR speed guns used by law enforcement.\n\nA LIDAR emits a characteristic modulated waveform from a laser.  The light travels to a surface, where it is reflected back to the LIDAR, and a receiver measures the time it took to make the trip (extremely fast).  Since the speed of light is a constant, the time can be calculated into a known distance.\n\nWith speed sensing LIDAR, two distance measurements are made in succession, and a distance/time calculation is performed to obtain the speed of an object (such as a car).

Motions are different types, linear,circular, eliptical, Simple hormonic motion,Non hormonic motion, etc. One type is vibrational motion.

google earth, will show you anyplace around the world.yes it's free and to can rotate and do whatever.

Well...\n\nhttp://volcano.und.edu/\nhttp://www.volcanoes.com/\nhttp://volcanoes.usgs.gov/\nhttp://vulcan.wr.usgs.gov/Volcanoes/\nhttp://pubs.usgs.gov/gip/volc/text.html\nhttp://en.wikipedia.org/wiki/Volcano\nhttp://www.usgs.gov/hazards/volcanoes/\nhttp://www.volcano.si.edu/world/\nhttp://www.cdli.ca/CITE/volcano.htm\n\nOkay, some of these rotate around grouped sites where many sites join together, but other than the USGS sites, I think most of these are individual... I haven't checked on them in a while, so yeah.

There are photoelectric and ionization types. See the ref.\nThe photodetector type shines a beam of light down a tube containing the air being sampled. A hole in the side of the tube passes any light that is scattered by smoke to the photodetector, whose amplified signal powers the alarm horn.\nIn the ionization type, a source of ionizing alpha radiation is beamed into an ionization chamber, where the nitrogen and oxygen molecules in the air sample become ionized and allow a small current to flow between the two plates that make up the chamber. When smoke is present, it disrupts the ionization process by attaching to and neutralizing the ions. The resulting reduction of current flow triggers the alarm.

With "Google Earth" you can see a radar image, but it will be fuzzy.  Try it, though.  It is fun for a few minutes, but you have to download it.

You could try a search on Google using "liquid lasers."\n\nSolid state, semiconductor, and gas lasers are more common than liquid lasers.\n\nMost liquid lasers are made with an organic dye - a kind of phosphorescent material suspended in a liquid.  Commercially available liquid lasers are usually called dye lasers, but not all dye lasers are liquid.\n\nFrequently liquid dye lasers are excited by a flashlamp.\n\nThe advantage of a liquid dye laser is that the output wavelength is "tunable," that is, you can select over a broad range what the output wavelength will be.\n\nI'll give a link in Sources to a recent article co-written by a friend of mine, Dave Titterton, who is a world renown expert in this field.  Go to link and click on the article called "From flashlamp-pumped Liquid Lasers to Diode-Pumped Solid-State Dye Lasers."

The head is a Class 1 laser diode fed by a constant current source of typically 20-50mA.  The beam is focused onto the CD surface and reflected back onto a photodiode with a risetime of 10nS or better.  The digital output signal is fed to a decoder and then to an amplifier.\n\nConcerning drives, the disc is spun at a constant speed by a pulse-feedback servomechanism.  The head travels radially much like the head on a harddisk.

there is a company called schrodinger, or something close t o that.\nthey make lasers measureing tools for the semiconductor and other industrues. they are in massachusetts.

Hmm. . its pretty rare stuff so you are not going to hand out samples\nSince it was once used in lasers you could start your presentation with a laser light show, or just a simple laser pointer\nPresent the information chronologically, show how and why it was discovered (it started as a blank square on the Periodic Table of the Elelments) talk about it uses and why it was replaced\ngood luck

Probably Radar - measuring the doppler shift (difference between transmitted frequency and reflexted frequency).\n\nDepending where you are, many police forces use laser systems these days. They are more precise and faster, but require someone to aim it at the target - not really suitable for a tennis ball!
