Rubidium Frequency
rubidium atom emits light whose frequency is 3.84x10 14hz is this light in the visible portion of the spectrum
if so, what color is it? can i get a brief exlanation too.
Yes it is the visible, by looking into the frequency spectrum,
http://en.wikipedia.org/wiki/Electromagnetic_spectrum
it's 3.84x10^14 right? you missed the cap
Get that into wavelength using the equation
c = λ × f
c-speed of light
λ-lambda - wavelength
f-freq
and compare it using a Visible Spectrum.

Color Wavelength
violet 380–450 nm
blue 450–495 nm
green 495–570 nm
yellow 570–590 nm
orange 590–620 nm
red 620–750 nm

Rubidium Hydride $65.33 Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Rubidium hydride is the hydride of rubidium. It is synthesized using rubidium metal to react with hydrogen gas. As a hydride of an alkali metal, it is reactive towards even weak oxidizing agents. A redox reaction will occur with chlorine or fluorine and a lot of heat will evolve. Rubidium hydride will react violently with water or air and careful storage is necessary. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F. Binding Type: Paperback Number of Pages: 64 Publication Date: 2011/03/18 Language: English Dimensions: 5.98 x 9.02 x 0.15 inches |

Rubidium Oxide $70.1 High Quality Content by WIKIPEDIA articles Rubidium oxide is the chemical compound with the formula Rb2O. Rubidium oxide is highly reactive towards water, and therefore it would not be expected to occur naturally. The rubidium content in minerals is often calculated and quoted in terms of Rb2O. In reality, the rubidium is typically present as a component of (actually, an impurity in) silicate or aluminosilicate. A major source of rubidium is lepidolite, KLi2Al(Al,Si)3O10(F,OH)2 wherein Rb sometimes replaces K. Rb2O is a yellow colored solid. The related species Na2O, K2O, and Cs2O are colorless, paleyellow, and orange, respectively. Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F. Binding Type: Paperback Number of Pages: 80 Publication Date: 2010/07/27 Language: English Dimensions: 6.00 x 9.00 x 0.19 inches |

Rubidium Chloride $65.33 Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Rubidium chloride is the alkali metal halide RbCl. This alkali halide finds diverse uses, from electrochemistry to molecular biology. In its gas phase, RbCl is diatomic with a bond length estimated at 2.7868 . This distance increases to 3.285 for cubic RbCl, reflecting the higher coordination number of the ions in the solid phase. Depending on conditions, solid RbCl exists in one of three arrangements or polymorphs as determined with holographic imaging. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F. Binding Type: Paperback Number of Pages: 64 Publication Date: 2011/03/18 Language: English Dimensions: 5.98 x 9.02 x 0.15 inches |

Secondary Frequency Standard $81.25 High Quality Content by WIKIPEDIA articles In telecommunications, a secondary frequency standard is a frequency standard that does not have inherent accuracy, and therefore must be calibrated against a primary frequency standard. Secondary standards include crystal oscillators and rubidium standards. A crystal oscillator depends for its frequency on its physical dimensions, which vary with fabrication and environmental conditions. A rubidium standard is a secondary standard even though it uses atomic transitions, because it takes the form of a gas cell through which an optical signal is passed. The gas cell has inherent inaccuracies because of gas pressure variations, including those induced by temperature variations. There are also variations in the concentrations of the required buffer gases, which variations cause frequency deviations. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Frequency - $9.99 Known more for his dark, psychological crime thrillers Primal Fear (1996) and Fallen (1998), director Gregory Hoblit surprisingly created this Frank Capra-meets-Rod Serling-style fantasy that mixes several genres of storytelling into a likable stew. James Caviezel stars as John Sullivan, a New York police detective who has never recovered from the death of his father Frank (Dennis Quaid), a firefighter who died heroically when John was a boy. Experimenting with his dad's beloved ham radio one summer night, extreme sunspot activity allows John to contact Frank 30 years in the past. Since he's able to warn Frank away from danger, his father's death never occurs. Then the unthinkable happens: John's altered future is one in which his mother Julia (Elizabeth Mitchell) has been murdered by a serial killer. Now John in the present and Frank in the past must try to solve the riddle of the killer's identity and change the time line again. Frequency was written by Toby Emmerich, the brother of actor Noah Emmerich, who appears in a supporting role created specifically for him. ~ Karl Williams, Rovi |

Atomic clocks
Atomic clocks are one of the most reliable time keeping devices today. This is accomplished by analyzing radio waves sent by the cesium atomic clock from the American National Institute of Standards in Fort Collins, Colorado, ensuring that your time is 100% accurate. Atomic clocks will also reset it for time-savings ensuring the accurate time remains.
As atomic clocks do run off of radio waves in Fort Collins, sometimes the waves me endure interferences such as large buildings with a significant amount of steel and limited windows. This may slow down the synchronization process; however the clock will still remain fully functional.
Another thing to consider before purchasing an atomic clock is that the clock will not receive the synchronization waves outside of the United States. This means that the clock will still be fully functional, however will not be syncing up to the exact time.
Clocks247.com offers a large variety of Atomic clocks from traditional wooden mantel clocks to high tech atomic clocks which are able to tell the temperature, days of the week, month, and multiple time-zones. Please visit http://www.clocks247.com/atomicclocks.aspx for a complete list of our atomic clocks.
In traditional clocks they rely on the balance wheel and hairspring of the clockwork watch, however with atomic clocks they rely on frequencies within the atom which are determined by the mass of nucleus and gravity electrostatic “springs” between the positive charge on the nucleus and the electron cloud which surrounds it. This method of time tracking keeps your atomic clock in sync at all times.
With an atomic clock there is no need to worry about power outages, time zones, or batteries going old which allows you to be assured that you always know the exact time.
There are several different types of atomic clocks. These types of atomic clocks are categorized by the element used to detect when the energy level changes within the radio waves. Cesium atomic clocks are able to analyze the radio waves by employing a beam of cesium atoms. The clock is designed to separate cesium atoms according to the different energy levels. This is accomplished through a magnetic field.
Hydrogen atomic clocks however maintain hydrogen atoms. These atoms require the energy level in a special container with walls and specific materials. This hand crafter container is designed so that the atoms don’t lose the higher energy states too quickly.
Rubidium atomic clocks are known as the simplest and most compact of all of the atomic clocks. This design uses a glass cell containing rubidium gas. The gas changes its absorption of light according to the microwave frequencies.
The cesium atomic clock is considered the most accurate atomic clock. These clocks utilize the cesium atoms in combination with normal magnetic fields and detectors. The cesium atoms are stopped from moving back and forth by laser beams, which in return reduces the small changes in frequencies due to the Doppler Effect.
Clocks247.com offers an extensive amount of atomic clocks including wall clocks, table top clocks, and mantel clocks. Please visit clocks247.com and buy your next clock. In addition to atomic clocks, clocks247.com offers wall clocks, alarm clocks, mantel clocks, floor clocks, melodies in motion, and office clocks.
