Amount Of Energy Stimulated Emission
1,113 wordsThere are only about 100 different kinds of atoms in the entire universe. Everything we see is made up of these 100 atoms in an unlimited number of combinations. They continuously vibrate, move and rotate. Even the atoms that make up the chairs that we sit in are moving around in class. Atoms can be in different states of excitation (Bertolotti 48) or they can have different energies. If we apply a lot of energy to an atom, it can leave what is called the ground-state energy level and go to an e...

Ozone Layer Ultraviolet Rays
1,294 wordsAtmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O 3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial and domestic chemicals ...

The Eye And Laser Surgery
1,567 wordsA Functioning Eye (Emmetropia) The eye is the organ of sight. It is used in almost everything we do, from playing sport to reading. A normal and well functioning eye can focus objects and images, both near and far, perceive depth and adapt to changes in light. The perception of depth is due to having two separate eyes creating two separate images, while the ability to adapt to light change is attributed to the iris and the dilator muscles. However these two aspects of the eye are not involved in...

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...

Stimulated Emission Positively Charged
948 wordsLasers HISTORY OF LASER PRODUCTION The roots of laser mechanism are very modern. In 1900 German physicist Max Planck presented an explanation of why the colors of a glowing hot body may change with temperature. He also proposed discrete quantum theory saying that radiations come in discrete quantities called quanta. Therefore radiations are not only a series of waves but a stream of particles called photons. By 1917, Einstein has outlined the principles underlying the production of laser radiati...

Chemical Reactions Three Types
890 wordsChemical Chemical Reactions CHEMICAL REACTIONS Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named George Ernst Stahl was the first to speak of chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the ai...

The most commonly overlooked piece of audio in a movie is the characters voices. The voices in Star Wars play a large part of the movie. Each character has a distinct voice and a distinct way that they speak. Darth Vader has an extremely deep voice and speaker in long draw out words, to help show how evil he is. Han Solo has a rugged sounding v...

Light Waves Light Rays
1,064 wordsToss a pebble in a pond -see the ripples? Now drop two pebbles close together. Look at what happens when the two sets of waves combine -you get a new wave! When a crest and a trough meet, they cancel out and the water goes flat. When two crests meet, they produce one, bigger crest. When two troughs collide, they make a single, deeper trough. Believe it or not, youve just found a key to understanding how a hologram works. But what do waves in a pond have to do with those amazing three- dimensiona...

Back And Forth Stimulated Emission
1,080 wordsThe light from lasers differs from ordinary light in several important aspects. Ordinary light from a light bulb travels randomly in all directions (unless the bulb is equipped with an integral reflector that directs the light). The light is thus incoherent. Even when incoherent light is directed with a reflector, it still spreads rapidly. The light from a laser is temporary and spatially coherent. This means that all of the wave-fronts of light are lined up in time and space (see Diagrams). The...

Nuclear Missiles Star Wars
583 wordsPresently, the threat of missiles is very dangerous. The missiles include biological, chemical, and of course, nuclear missiles. Our nation, the US, is one of the richest and most powerful nations on the world. Since we are so strong, many countries threaten us and endanger the citizens. Lately, a system called the Star Wars SDI was initialized during the Reagan Administration. The system involves lasers that will fry the chips in missiles. That will cause the missile to stop in its flight and n...
