The Physics of a Crystal

Most simple chemical compounds consist of crystals. If you were to examine a lump of crystalline material very closely, you would be able to see tiny individual crystals. All crystals have a definite geometric shape, determined by the way the atoms are linked together.
     Mineralogists recognize 32 different classes of crystal, which are grouped into seven crystal systems. Crystal systems are described by their axis, which are imaginary lines that join the center of opposing faces of a crystal. For example, if a cubic crystal has three sets of opposing faces, it has three axes. They are all of equal length and are all at right angles to each other.
Cubic crystals are described as being isometric, but not all isometric crystals are plain cubes. If the corners of a cube are cut off, the result is a polyhedron with six octagonal faced and eight triangular ones.
Aside from the isometric system, there is also; a tetragonal, orthorhombic, monoclinic, triclinic and hexagonal system.
Crystals may form when a solution of a substance evaporates. Crystals may also form when a vapor or molten substance solidifies.
Allotropes are different forms of the same element. For Example, oxygen has two allotropes, normal oxygen and ozone. Pure carbon also has two allotropes, diamond and graphite. A crystal of diamond is in fact a single giant molecule in which every carbon atom is linked to four other, by four equal, strong bonds. These bonds are arranged tetrahedrally round each atom and there are no planes along which the giant molecule can easily be split. This quality is what gives diamond its tremendous hardness.

Essay on The Physics of an AM Radio - The Physics of an AM Radio It’s was a beautiful sunny morning and Bill just kissed his wife goodbye and headed out the door on his way to work. As Bill got into his car he realized that he missed the Utah Jazz game the night before because of a late business meeting and fell asleep before the news came on so he couldn’t catch the highlights or even the score. He remembered that he could catch the rundown on AM frequency 930 (Sports News Radio). Many people enjoy listening to AM radio because of how convenient it is to listen and catch up on the sports, weather or just enjoy the entertainment of listen to Rush or Dr....   [tags: Physics Radio Papers]

Physics of Snow Essay - The most basic form of an ice crystal is a hexagonal prism. This form occurs because certain surfaces of the crystal, the growth facets, grow very slowly. The reason these facets exist derives from the molecular structure of water, and how water molecules arrange themselves into a crystalline lattice. The hexagonal prism includes two hexagonal "basal" faces and six rectangular "prism" faces. Note that the hexagonal prism can be "plate-like" or "column-like", if the length along the c-axis is short or long compared to the length along the a-axes....   [tags: physics snow] 2464 words

Physics of Avalanches Essay - Avalanches are just one of many natural disasters that kill people every year. The difference to Alaskans is that this disaster hits a little closer to home than most. The fear of hurricane and tornado are not existent in my region, and even earthquakes are seen more as a little shake then any threat. Physics plays a huge part in avalanches, thermodynamics, statics, and gravity are just a few elements of these disasters. The map above confirms that Alaska is at high risk for avalanche. As a result of this threat, learning about avalanches is a necessity when recreating or working in high avalanche areas....   [tags: physics snow avalanche] 1442 words

Essay on Physics of the Turntable - The word turntable is the modern term used to describe what is known as the phonograph, gramophone, or record player. The first turntable was invented by Thomas Edison in 1877. It was the first device used for recording and playing back sounds. Modern turntables have the same fundamental components as their ancestors, albeit slightly more sophisticated in design. This paper covers the fundamental technical aspects of modern turntables. A modern turntable basically works like this: A platter (on which the record sits) is spun by a drive system....   [tags: physics turntable music] 1224 words

A Real-time Scintillation Crystal Identification Method and Its FPGA Implementation - A popular method for gamma ray detection utilizes scintillation detectors which consist of crystals optically coupled to a photomultiplier tubes (PMTs). Scintillators are widely used in the medical radiation fields such as CT scanners, gamma cameras and positron emission tomography (PET) scanners ‎[1]-‎[5]. The scintillation crystal responds to the absorption of gamma ray by the emission of a light pulse. This light pulse is characterized by the special properties of the crystal such as the decay time constant....   [tags: gamma ray, energy, domain]

Essay on Physics of Sea Ice - Sea ice is frozen sea water. Salt ions in the water complicate the growth of ice crystals, and makes sea ice much more dynamic than freshwater ice. Sea ice covers nearly 7% of the Earth's surface, has a huge effect on global climate, and is one of the largest, single biomes on Earth. Ice is the solid, crystalline form of water, which solidifies at 0ºC. Roughly 9 polymorphs of ice are defined, only one, however, occurs naturally on Earth. This common form of ice is known as ice 1h, and its lattice displays six-fold rotational symmetry....   [tags: physice ice sea] 872 words

Essay on Principles of Physics in Ultrasound - Principles of Physics in Ultrasound Physics has become an important part of medicine allowing specialist doctors and radiographers to rapidly access a patient’s condition and to help in long-term diagnosis. This enables doctor’s to treat patients before their condition deteriorates. This procedure would not be possible without the use of X-rays, CAT scans, MRI scans, ultrasound and endoscopes, which allow doctors to see inside the body with little or no surgery. Without such equipment doctors would be forced to use invasive techniques, which could cause patients more harm as it increases the risk of infection....   [tags: Papers] 1732 words

Graphite on the other hand, consists of flat sheets of carbon atoms arranged in adjoining rings. Each carbon atom is linked to three others by fairly strong bond that all lie in the same plane. These can easily be overcome, allowing the sheets to slide over each other. As a result, graphite is a soft slippery substance that can be used as a lubricant.
