Electromagnetic Radiation Infrared Radiation
1,377 wordsYou might remember the heroic role that newly-invented radar played in the Second World War. People hailed it then as "Our Miracle Ally." But even in its earliest years, as it was helping win the war, radar proved to be more than an expert enemy locator. Radar technicians, doodling away in their idle moments, found that they could focus a radar beam on a marshmallow and toast it. They also popped popcorn with it. Such was the beginning of microwave cooking. The very same energy that warned the B...

Radio Telescopes Radio Waves
1,285 words... copes Orbiting telescopes are used to observe the ultraviolet (UV), far infrared, and X-ray portions of the electromagnetic spectrum. The Infrared Astronomical Satellite, placed in orbit in 1983, carried a 22. 5 -inch infrared telescope. Because all matter emits infrared radiation if warm, technologists had to cool the telescope to near absolute zero with liquid helium so its internal heat radiation would not mask radiation it was collecting from deep space objects. Among its many discoverie...

Physical Side One Time
866 wordsThere are many kinds of networks, however this paper will be about networking computers. As we move further and further into the paperless society, the need for people to be connected and able to exchange data just as fast as they could by handing a paper to someone increases. This can be accomplished by having a group of computers connected by a network, so that as soon as data is entered into one computer, it can be immediately accessed by someone else on a connected computer, no matter how fa...

Solid State Lasers Gas Lasers
393 wordsThere are many different types of lasers. The laser medium can be a solid, gas, liquid or semiconductor. Lasers are commonly designated by the type of lasing material employed: Solid-state lasers have lasing material distributed in a solid matrix (such as the ruby or neodymium-yttrium aluminum garnet (YAG) lasers). The neodymium-YAG laser emits infrared light at 1, 064 nanometers (nm). A nanometer is 1 x 10 - 9 meters. Gas lasers (helium and helium-neon, He Ne, are the most common gas lasers) ha...

Chlorofluorocarbons Cfcs Ozone Depleting
1,295 wordsThe ozone layer is one of the oldest things on the planet, older than any of the ancient creatures we see in our museums today. The ozone layer has provided protection for the living components under it for millions of years, and without the ozone layer, we most likely would not be here today. Our evolution would have been cut off millions of years ago without our planets ability to provide protection from the ever-harmful rays from our sun. Each year since the late 1970 s much of the protective...

Surface Of The Earth Released Into The Atmosphere
328 wordsatmosphere is to insulate and warm the surface of the earth. The greenhouse effect is not a new phenomenon. Humans can help reduce the increasing greenhouse effect. The atmosphere insulates and warms the surface of the earth. Incoming solar radiation passes through the atmosphere. The surface of the earth absorbs some of the radiation. The unabsorbed radiation is emitted back out in the form of infrared radiation. Gases, such as, carbon dioxide, methane, nitrous oxide, and water vapor absorb the...

Fibre Crystal Mid Infrared Lasers
1,998 wordsFibre crystal mid-infrared lasers As we know, a laser is an optical oscillator made out of a gas, liquid or solid with mirrors at both ends (see, e. g. , The Computer Language Company Inc. , 2007 b). To make the laser work, the material is pumped with light or electricity. This pumping has excited the electrons and has caused them to jump to more high orbits. Some electrons do spontaneously drop back to lower energy levels what releases photons (i. e. quantum's of light). The photons do then sti...

Control Panel Break Ins
6,908 wordsIntroduction There have been a number of burglaries in the area in which the Peterson family are living; thus they have become increasingly interested in Control Technology in their home. ? They have contacted me, and my task is to prepare a report, which advises them upon various alarm systems, also considering fire detection systems. I am going to provide the Peterson? s with two reports, one outlining a basic security system for the family, and the other a more advanced top of the range syste...

Infrared Light Blue Green
344 wordsThe Basics. Sunlight plays a much larger role in our sustenance than we may expect: all the food we eat and all the fossil fuel we use is a product of photosynthesis, which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms, ranging from plants to bacteria (Figure 1). The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by cyano...

Methane Nitrous Oxide Rise In Sea
1,611 wordsThe Greenhouse Effect The greenhouse effect is an increase in the atmospheric temperature caused by increasing amounts of greenhouse gases. These gases act as a heat blanket insulating the Earths surface absorbing and trapping heat radiation which normally escapes from the earth. They include carbon dioxide, water vapour, methane, nitrous oxide, CFCs, and other halo-carbons. The earths atmosphere goes through two processes constantly. Global cooling is the first process. This process uses the cl...

Greenhouse Gases Infrared Radiation
431 wordsGreenhouse Effect Greenhouse Effect, term for the role the atmosphere plays in insulating and warming the earths surface. The atmosphere is pretty much transparent to incoming solar radiation. When this radiation strikes the earths surface, some of it is absorbed, warming the earths surface. Earth s surface emits some of this energy back out in the form of infrared radiation. As this infrared radiation travels through the atmosphere, most of it is absorbed by atmospheric gases like carbon dioxid...

Burning Fossil Fuels Average Global Temperature
1,498 wordsGreenhouse Effect The greenhouse effect is a natural phenomenon that warms the earth and enables it to support life. Without it, the average temperature on earth would be around - 18 degrees C, instead of the current + 15 degrees C a frozen wilderness. It works on the same principles as the ordinary glass garden greenhouse, where glass allows light to get in, but does not allow for the heat to get out. This makes for a much higher temperature inside the greenhouse. On a planetary scale, similar ...

546 wordsThe Biggest Environmental Problem The environmental problem that must be considered as the biggest, is the Global Warming. Temperature is slowly increasing all over the world. To understand this better it is also important to explain the greenhouse effect. The greenhouse effect in a summary: Sunlight radiates from the sun, through space, to earths atmosphere. The sunlight enters the atmosphere and hits the earth. Some of it turns to heat energy in the form of infrared light. The heat absorbs by ...
