    Undergrad Still a bit confused about electron orbitals?

    Hey Everyone, If you have an electron with the various energy levels: -14 eV, -30 eV, -52 eV, -80 eV. And that the electron can only move between these levels. How do I go about finding the photo energy that is emitted? Do I just subtract the various levels? Ex. 14 - 30 = -16 etc?

    Undergrad Calculate De Broglie Wavelength of Electron | Help for Final Exam

    Hmm according to the hyperphysics website, my answer should have been 1.85079 x 10 ^ -25 would that be right? All i did was input the ev value of 40, but I did not input anything for mass or velocity.

    Undergrad Calculate De Broglie Wavelength of Electron | Help for Final Exam

    I'm reviewing for one of my final exam and I can't seem to figure out this problem: Find the Debroglie wavelength of an electron with a KE of 40 ev. I got an answer of 3.9 x 10^-10 m. I keep getting it wrong and I'm not sure what to do. Thanks in advance!
