Cesium Definition and 15 Threads

Let me start out by saying that I have no idea what I'm talking about. I graduated from Indiana University with a Bachelor's in Spanish, and I work as a Loan Review Specialist at a bank, which has NOTHING to do with my degree, and still yet nothing to do with this topic. But lately, I've become...

Because metals have free electrons, so they have almost continuous energy states going up and down different energy levels and repeating themselves, most metals are silver-white, right?But why do gold, copper, and cesium have special colors? I wanted to know more about this, so I studied the...

Why do GPS need a cesium clock accurate to 10ns? Is this strictly for time keeping or is there some synchronization between satellites?

Homework Statement A sample of a compound of cesium (Cs) and iodine (I) contains 51.16g cesium and 48.84 g iodine, how many grams of cesium can be obtained from 85.5g of this compound? The attempt at a solution I don't really know where to begin. What I have tried was the following: 51.16 g +...

Hi everyone this is my first time posting here, First of all, excuse my english because here in Mtl we speak French mostly. My team and I are working on an university project in Montreal (Qc) Canada (Polytechnique) regarding the recycling of radioactive material waste. We are working on the...

I just read the thread entitled: "How did Einstein Define Time" and I'm very confused. At school, I was taught that time was an abstract representation of movement meaning that the word "time" can only be used to represent movements. For example, when Earth has completed a cycle around the...

I am reading a book called advanced physics, which is very good I may add. there is a question in it as follows; The second is defined as 9,192,631,770 periods of radiation from a caesium-133 atom, The metere is defined as the distance traveled by light in 1/299792458 of a second. How many...

Hello guys, I need the quantum mechanical description of the Cesium atom/gas with its hyperfine states, and preferably with some density matrix. I don't really know where to start my search. I googled a lot, and looked for articles and books, but failed. Any help is highly appreciated...

Hello guys :), if we magnetise Cs atoms with a magnetic field (or basically any other method like pumping), and got all the spins (moments) aligned in 1 direction, and then turn the cause of the alignment off, how will the decay profile look like? is it going to be a clean exponential decay...

I recently read http://www.google.co.in/search?source=ig&hl=en&rlz=&=&q=speed+of+light+in+caesium+vapors&btnG=Google+Search" that speed of light is faster in cesium vapors. It is described as leaving the cesium container even before it has entered it, claims that light travels 310 times faster...

Can anyone recommend me some papers explaing how cesium atomic clock works?

Cesium is often used in "electric eyes" for self-opening doors in an application of the photoelectric effect. The amount of energy required to ionize (remove an electron from ) a cesium atom is 3.89 electron volts (1 eV = 1.60 x 10-19 J). Show by calculation whether a beam of yellow light with...

I am working this problem... http://www.fiu.edu/~saulj/Teaching/Physics2/01-Electric_Force/CrystalStructure.html I got the answer to a as 0, but don't understand b.

http://physicsweb.org/articles/news/10/10/6/1?rss=2.0 ===sample=== 5 October 2006 Danish physicists have managed to light-up a cloud of atoms using light teleported from a source half a metre away. Since Charles Bennett and his team first proposed quantum teleportation in 1993, science...

It goes like this, very simple: How and where can cesium and thallium be used?
