Solid State Lasers Back And Forth
2,014 wordsLaser is an acronym for light amplification by stimulated emission of radiation. In the last century many types of lasers have been used for many different applications from welding to surgery to military and even many uses in every day life by harnessing the principles of light and stimulated emission. To understand how lasers work we must first understand the physics behind light waves. Light is emitted from a source and travels in straight lines and when it strikes an object is either absorbe...

Subatomic Particles Quantum Mechanics
756 wordsQuantum Mechanics is the science of subatomic particles and their behavior patterns that are observed in nature. As the foundation of scientific knowledge approached the start of the twentieth century, problems began to arise over the fact that classic physical ideas were not capable of explaining the observed behavior of subatomic particles. In 1913, the Danish physicist Neil's Bohr, proposed a successful quantum model of the atom that began the process of a more defined understanding of its su...

Seismic Sea Sea Floor Water
550 wordsA tsunami is a wave train, or series of waves, generated in a body of water. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis. These waves can savagely attack coastlines, causing devastating property damage and loss of life. In English, the word tsunami means "harbor wave. " Represented by two characters, the top character, "tsu, " means harbor, while the bottom character, "nami, " means "wave. " In the past,...

Shield Volcanoes Plate Tectonics
1,406 wordsWhen there is a sudden breaking of rocks within the earth or an explosion, wave like energy travels through the earth and is recorded on seismographs. These are called seismic waves and they are of two types: body waves and surface waves categorized into different kinds. What we will be discussing are body waves; there are two types of body waves: primary waves (P waves) and secondary waves (S waves). Both kinds travel through the Earths interior in all directions and arrive before the surface w...

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...

Earths Crust San Francisco
1,193 wordsAn earthquake is shaking or trembling of the earth that is volcanic or tectonic in origin. A broadly satisfying explanation of the majority of earthquakes can be given in terms of what is called plate tectonics. The basic idea is that the Earths outermost part also called the lithosphere consists of several large and fairly stable slabs of solid and relatively rigid rock called plates (Bravely 154). These plates continuously move pushing and rubbing against each other. Since the earliest of time...

Larger earthquakes usually begin with slight tremors but rapidly take the form of one or more violent shocks, and end in vibrations of gradually diminishing force called aftershocks. The subterranean point of origin of an earthquake is called its focus; the point on the surface directly above the focus is the epicenter. The magnitude and intensity of an earthquake i...

At the time, I didn t quite realize that quantum theory and quantum physics were related except in name. Niels Bohr once said, Anyone who is not shocked by quantum theory has not understood it. He believed this because quantum physics makes the common laws of classical physics false on small scales. First, quantum physics is the physics of the incredibly small. It tries to explain the ...

402 wordsWaves Sound Waves Sound Waves Waves are disturbances that travel through a space while changing its matter. A sound wave is what allows us to hear sounds. It is created by vibrations, which are made by the movement of matter. Sound waves must travel through a solid, a liquid, or a gas. The more tight the particles, the faster the wave will travel. This would mean that a sound wave travels fastest through solids and slowest through gases. The speed that it travels through a liquid would come some...

Surfers Tend To Stand Face Of The Wave Board
397 wordsSurfing Surfing is a water sport that originated in what is now Hawaii. People in Hawaii were surfing before explorer Christopher Columbus sailed to the New World in 1942. Today, surfing is popular in many countries, including Australia, Brazil, France, Indonesia, Japan, Portugal, Peru, South Africa, and the United States. Ancient Hawaiians surfed on wooden boards that were up to 18 ft. Long. With the development of lighter boards, however, surfing became a popular sport. By the 1930 s the solid...
