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...

Each signal type is implemented in circuitry with accompanying software, called a transceiver. The transceiver design includes the encoding or modulation scheme along with decoding or demodulation applied to convert serial binary data streams into a form suitable for transmission through twisted wire pairs. The transce...

Sodium Hydroxide Universal Indicator
854 wordsExperiments to Determine the Effect of Acids & Bases on Different Indicators and the pH of Common Cleaning Agents The aim of the first set of experiments is to find out and record the colour changes that are observed after a certain indicator is mixed with acids and bases to form a colour reaction. Once the selected indicator has been mixed with a acid that is both weak and strong and a base / alkali that is both weak and strong we are to record the colour and choose another indicator. The purpo...

Niels Bohr Model Of The Hydrogen Atom
365 wordsNiels Bohr's model of the hydrogen atom, was the primary reason for the understanding of energy levels. Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form of light. He figured the light rays to be quantized, meaning only certain frequencies ...

Epic Vs Modern Heroes
1,029 wordsWhile Have at thee! the Arthurian battle cry from Monty Pythons Search for the Holy Grail, is a far a-hem cry from the modern day heros, the essence remains the same. Many aspects of culture have been wholly altered, but society's quest for a hero has remained. Each people of the ancient times had a matchless idol that was unto his self the embodiment of cultural perfection. In more recent eras, where societies vary exceedingly, people have relied on scores of heroes. The United States is deemed...

(Siddiqui par. 32) Many terrorists do want to burn the U. S. and are willing to die for their beliefs. These suicidal anti-Americans will never be persuaded to change their minds....

Earthquake Loads Resistant Design Of Buildings
2,074 words... Spectra are developed by calculating the of response a single mass oscillator (usually with 5 % critical damping present) to the design level earthquake motion. Engineers traditionally have shown a preference for acceleration spectra, since the resulting coefficient, when multiplied by the seismic mass, results in the lateral base shear for the building. In Australia [ 7 ] and the Uniformed Building Code used in the western USA [ 9 ] these spectra are presented as a simple uniform coefficien...

Racial Affiliation Bell Curve
386 wordsPsychology Essay It has been noticed that people with different ethical backgrounds react differently to the same set of circumstances. Slowly, the psychologists began to realize that this can be attributed more to peoples racial affiliation then to the socio-economical aspects of their upbringing. Let us describe the most important differences and similarities in cross-cultural expression of emotions. People of European descend are known to be the least emotional of all. As a matter of fact, ma...

The sky is filled with air which is a mixture of tiny gas molecules and small bits of solid stuff, like dust (Why Is the Sky Blue? ). The air constitutes the atmosphere, a gaseous shell surrounding the Earth and some other planets. The main gaseous components of the atmosphere are nitrogen (78. 09 %) and oxygen (20. ...

2,792 wordsFourier Analysis Fourier analysis of spatial and temporal visual stimuli has become common in the last 35 years. For many people interested in vision but not trained in mathematics this causes some confusion. The use of these Fourier methods does not mean that the visual system performs a Fourier analysis. At present it should be understood that this approach is a convenient way to analyze visual stimuli. Jean Baptiste Fourier, a mathematician, showed that any repetitive waveform can be broken d...

H 2 O Carbon Dioxide
854 wordsColours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1. 1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in ...
