The deBroglie wavelength as fe was a typo, I meant frequency. I now notice that I without really thinking about it assumed E=hf applied for the electron. I cannot this? (The book's definition of deBroglie wavelength is h/p, yes)

Hi, I got the following question in my textbook: [translated]"Compare the wavelength of a photon and an electron where the photon and the electron have the same momentum". My thinking is the following: Firstly, pp (photon) = pe (electron). My textbook briefly mentions the extention of the...

I tried this out and got it working! And it made a lot of sense, Thanks! Assuming the electron is obeying bohr's model of the atom its centripetal acceleration a = F / m, and by a = v2 / s, v = √(a s). The kinetic energy Ek = ½ m v2 = ½ e2/s 8.988*109 ≈ 2.18*10-18 J. This makes the extra energy...

Hi, I've just gotten started with basic quantum physics in physics class and we've just talked about ionization energy. It is stated that the energy of a hydrogen atom is -13.60eV (or -2.179aJ). I assume this is the potential energy (and that this is the reason the atom has a lower mass than the...

(I did not intend this to end up in introduction so I changed the thread to an introduction. Ehm should I revert back to the question or keep both. I screwed up D:) I know a little about the quantum smudge, yes, but shouldn't the radious stated in my textbook be the average distance? And thus...

Hi, I'm a Swedish student studying information technology with a great interest for physics and mathematics. I hope to be learn new interesting things and hopefully be able to help out a little too with the knowledge I have :)
