- Rarefaction is the reduction of an item's density, the opposite of compression.[1] Like compression, which can travel in waves (sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave (see picture).

- A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source.

Interference and Beats And as a rarefaction passes through a section of a medium, it tends to push particles apart, thus creating a low-pressure region. The interference of sound waves causes the particles of the medium to behave in a manner that reflects the net effect of the two individual waves upon the particles.

Microscope Glossary Phase contrast microscopy, first described in 1934 by Dutch physicist Frits Zernike, is a contrast-enhancing optical technique that can be utilized to produce high-contrast images of transparent specimens such as living cells, microorganisms, thin tissue slices, lithographic patterns, and sub-cellular particles (such as nuclei and other organelles).

Longitudinal Wavelength of Sound Waves Sound waves have two phases, compression and rarefaction, or decompression. When you look at snapshot of a pressure wave, you'll see points where compression and rarefaction are taking place. Compressions are places where the carrier medium is denser than at equilibrium.

- Sufficiently pure aluminum is superconducting at 1.2 Kelvin. Many of the pure elements are superconductors at sufficiently low temperatures, but some of them require special c … onditions, such as platinum. Platinum doesn't superconduct unless it's in nanoparticles.he negitive about things. A drawback means a disadvantage to an action or policy.

What are Sound Waves? - Definition, Types & Uses It is the peak of the wave. A rarefaction is a low density part of the wave-the part where the slinky is most spread out. This is the trough of the wave. One difficult part of understanding this topic is the question of why these compressions and rarefactions are considered to be a wave at all.

superconductivity Superconductivity is the ability of certain materials to conduct electric current with practically zero resistance. Superconductivity is the ability of certain materials to conduct electric current with practically zero resistance. This capacity produces interesting and potentially useful effects. For a material to behave as a superconductor, low temperatures are required. Superconductivity was first observed in 1911 by H. K. Onnes, a Dutch physicist. His experiment was conducted with elemental mercury at 4 degrees kelvin (approximately -452 degrees Fahrenheit), the temperature of liquid helium.

- adjective (rarer, rarest). 1 (Of an event, situation, or condition) not occurring very often: a rare genetic disorder [with infinitive]: it’s rare to see a house so little altered. More example sentences. Synonyms. 1  The best that most of us can do is to live with it, enjoy it and be thankful it is such a rare event.

Soil liquefaction Soil liquefaction describes a phenomenon whereby a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a liquid.his is because a loose soil has the tendency to compress when sheared, generating large excess porewater pressure as load is transferred from the soil skeleton to adjacent pore water during undrained loading. As pore water pressure rises a progressive loss of strength of the soil occurs as effective stress is reduced.

rare If an event is rare, it doesn't happen often. If an object is rare, there aren't many of its kind. Obviously, finding a rare gem is a rare occasion. Rare comes from the Latin word rarus, meaning “widely spaced,” as rare things are — whether in actual space or in time. You thought it was rare to meet someone you have so much in common with, until he fainted looking at the rare steak you ordered.

Superconductivity A high-temperature superconductor levitating above a magnet. Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature.It was discovered by Dutch physicist Heike Kamerlingh Onnes on April 8, 1911 in Leiden.n superconducting materials, the characteristics of superconductivity appear when the temperature T is lowered below a critical temperature Tc. The value of this critical temperature varies from material to material.

What Are Rare Earths? Rare earths are a series of chemical elements found in the Earth’s crust that are vital to many modern technologies, including consumer electronics, computers and networks, communications, clean energy, advanced transportation, health care, environmental mitigation, national defense, and many others.candium, a silvery-white metal, is a non-lanthanide rare earth. It is used in many popular consumer products, such as televisions and fluorescent or energy-saving lamps. In industry, the primary use of scandium is to strengthen metal compounds.

Paleomagnetism Paleomagnetism (or Palaeomagnetism in the United Kingdom) is the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials. Certain minerals in rocks lock-in a record of the direction and intensity of the magnetic field when they form.

Understanding Metamorphic Facies Definition: As metamorphic rocks change under heat and pressure, their ingredients recombine into new minerals that are suited to the conditions. The concept of metamorphic facies is a systematic way to look at the mineral suites in rocks and deduce the pressure and temperature (P/T) conditions that made them.
