What element which is used in atomic clocks and photocells melts at temperatures slightly above room temperature?
Cesium
What element is used to make very accurate atomic clocks?
strontium or cesium
What is used in making atomic clocks that lose one second every 300 years?
Perhaps caesium (cesium) is the answer.
How atomic clocks work?
Atomic clocks, rather than use gears or quartz movement as a timing standard, use electromagnetic waves as timing standards. Often the transition frequency used is in the microwave spectrum. This makes them extremely accurate since they use such very small units.
What is the difference between an atomic clock and an ordinary clock?
An atomic clock is a clock that uses an electronic transition frequency in the microwave, optical, or ultraviolet region of the electromagnetic spectrum of atoms as a frequency standard for its timekeeping element. Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS.
What element which is used in atomic clocks and photocells melts at temperatures slightly above room temperature?
Cesium
What element is used to make atomic clocks?
The atom of the isotope caesium 133; the definition of second in SI is based on this atom.
What element is used to make very accurate atomic clocks?
strontium or cesium
What element is used to make light sensitive photocells electric eyes and fire alarms?
Selenium
One of the most metallic metals named for its sky blue spectral lines atomic clocks using this element are accurate to 5 sec in 300 years or 1 sec in 60 years?
The element used in highly accurate atomic clocks is cesium. It is radioactive and has a well-know half life. This element seems to work the best in this manner.
Element used in photoelectric cells and in atomic clocks?
abcdefghijklmnopqrstuvwxyz
What is the element first used for fission in the atomic bomb production?
The element first used for fission in an atomic bomb is uranium.
What information was used to assign the atomic number to a particular element?
The atomic number of an element depends on the number of protons in that element.
What element is used to make light sensitive photo cells for camera electric eyes and fire alarms?
It used to be Selenium, but modern photocells use silicon (Si).
Clock used by national bureau of standards?
The National Bureau of Standards and Technology uses the Atomic clock. These clocks are said to be the most accurate clocks.
Whats the US atomic clock?
Atomic clocks are in Federal Office of Metrology-Bern-Switzerland, National Physical Laboratory-Teddington-London-United Kingdom and at National Metrology Centre-Singapore. Atomic clocks are also in other countries as well.
Used in the making of atomic clocks that lose one second every 300 years?
Cesium
