2) "(The binding energy of the K shell in tungsten is 69.5keV. The binding energy of the L shell in a tungsten atoms is 10.5 keV)." This statement should say: element W K-shell binding energy is 69.5250keV. Element W L-shell has 3 subshells, their binding energies are: L1is12.100keV, L2 is...

Q: "Homework Statement A K shell electron is ejected from a tungsten atom. The result of this is the emission of a characteristic x-ray proton. (The binding energy of the K shell in tungsten is 69.5keV. The binding energy of the L shell in a tungsten atoms is 10.5 keV)." A: 1) "characteristic...

Hi Lee. You asked: "But, what happens after that? A gap in, say, the L-shell has now been created. If the atom is big enough, does this mean that an electron from M or N then fills THAT gap, emitting a photon, and so on until... what? Until you have an ion in its most stable state?" Answer: Yes...

Sounds like you are looking for information on the Beer-Lambert law, more specifically the Lambert's cosine law: groups.csail.mit.edu/.../6.837/F01/Lecture15/lecture15.pdf

Please refer back to response #26. ooops...My error. You are correct, I read the article at the beginning just now. It does say relativistic. My response was to the OP question and was only trying to help him. Quantum Physics it is. Not my thing. I get it finally, I can't talk quantum and you...

You didn't specify relativistic speeds. We were talking about Solar Wind (~ 1 million miles per hour). Not near the speed of light. Is this forum only for quantum physics, or is classical everyday physics allowed? Perhaps I misunderstood. Geo

Is the static magnetic field at right angles to the motion of the electron, or some other angle? Right angle presents a circular e- path, other angles present a spiral, as shown in the video. Geo

Induction. a.k.a. electromagnetic induction. Geo

I hope I'm using "quote" correctly, if not please give guidance... Are you asking if the curved path intrinsically reduces energy vs. a straight path? Otherwise, yes even photons can alter an electron's energy state markedly, it doesn't have to be another particle of matter. Geo

In the above post, the OP said: "As I inferred implied moments ago, I've studied electron beam deflection in a cyclotron. Your video doesn't make me understand anything more perfectly, as it's basically the same thing. " Dear OP. If you've studied cyclotron theory, you know that electrons...

You asked: "Milliohms? :bugeye: Do you have a way of testing these resistors? I'm guessing a wheatstone bridge?" Yes right on. a guarded Wheastone bridge bu ESI for high resistances up to 12,000 MegOhms, and an ESI Kelvin Bridge for the very low stuff (old tech but accurate), also a pair of...

Thanks for clarification. Geo

Help me out here, I'm a little confused. Someone posted this link in this thread earlier: https://www.abc.net.au/news/2019-08-09/russian-rocket-explosion-kills-two-sparks-radiation-concerns/11398604 Inside is a video with this caption: Video: The rocket explosion comes days after a fire at a...

Correct, X=10 ESI was merged several times, the main survivor today of the corporate takeovers is IET Labs. Accuracy when Tegam made them = Specifications CHARACTERISTIC SPECIFICATION Accuracy Resistance Increments See Table 1 Initial (0.01% + 7 milliohms) Long-term (0.02% + 10 milliohms)...

I'm no scholar but we do use silicon and germanium detectors in the radiation detection lab. Most of those must be operated in total darkness, because they also respond to visible light, as they are actually photocell technology. If you are the OP and this seems like something you might be...
