Blue Light Significant Difference
1,039 wordsThe Effects of Various Wavelengths on Photosynthetic Rate Photosynthesis is the process by which autotrophic organisms convert light energy to chemical energy in the form of glucose [ 1 ]. Without this process life on earth would be very different because every organism directly or indirectly depends on photosynthesis. Because plants are at the bottom of the food chain they must create their own energy; this is done through photosynthesis. Various pigments located through out the leaves and stem...

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...

White Light Red Green
1,468 wordsColor is the curves, where the height of the curve represents the amount, or intensity, of that particular wavelength. Everyone of these distribution curves then corresponds to a color of light. Many of the colors we are familiar with appear on the EMF visible spectrum, such as red and yellow. We would therefore expect the distribution curves of these colors then to have a positive value only at a certain wavelengths. Under most conditions this is not true there are usually traces of all the oth...

Fiber Optic Cable Fiber Optics
4,355 wordsOur current age of technology is the result of many brilliant inventions and discoveries, but it is our ability to transmit information, and the media we use to do it, that is perhaps most responsible for its evolution. Progressing from the copper wire of a century ago to todays fiber optic cable, our increasing ability to transmit more information, more quickly and over longer distances has expanded the boundaries of our technological development in all areas. Todays low-loss glass fiber optic ...

Cycles Per Second Magnetic Fields
2,862 wordsThe Effects of Living Under Electro Magnetic Fields Power Lines Electric power is a fact of life in America in the world today. Ever since electric power was introduced society has thought nothing of the harmful effects of electromagnetic fields or electricity as long as they had it at their disposal. I will not be able to answer the question for you about how harmful it is but I will be able to enlighten you with information to help you decide how harmful it really is. For many years there have...

Parts Per Million Chlorofluorocarbons Cfcs
3,718 wordsIntroduction Orbiting Ozone Layer Ozone Layer Introduction Orbiting above the Earth, an astronaut can look down on our home and see the thin blue ribbon that rims our planet. That transparent blanket our atmosphere makes life possible. It provides the air we breathe and regulates our global temperature. And it contains a special ingredient called ozone that filters deadly solar radiation. The Atmosphere The gaseous area surrounding the planet is divided into several spherical strata separated by...

Radio Waves Light Waves
335 wordsRadio astronomy uses radio waves to study regions of space. Radio waves are a form of electromagnetic radiation like visible light waves only with much longer wavelengths. Visible light waves are oscillating electromagnetic signals with wavelengths of less than one millionth of a metre, whereas radio waves have wavelengths in the range of a few millimetres to several metres. Radio telescopes gather and concentrate the radio waves from an astronomical source. The signal received is then electroni...
