Aca atom (atomic number = 20) is in the ground state. light is shined on the atom, exciting the most energetic electron. which of the following arc possible quantum numbers (n, l,m) of this excited electron? we omit the electron spin quantum number. (4,0,0) (4, 1, -1), (4, 1, 0), and (4, 1, 1) (5, 2, +1) and (5, 2, -1) all of the above none of the above you are given a collection of quantum dots (treat as 1-d infinite square wells) and a collection of diatomic molecules (treat as simple harmonic oscillators). you find that the same wavelength of light will excite both the quantum dots and the molecules from their ground states to their first excited states. what is the ratio of the photon energies required to further excite each system from the first excited state to the second excited state? equantum dot/emolecule = 1 equantum dot/emolecule = 6/5 equantum dot/emolecule = 5/3 equantum dot/emolecule = 15/2 the information given is not sufficient to answer this question. electron spin resonance (esr) is a technique much like nuclear magnetic resonance (nmr). except that it relies 011 using radio-frequency photons to flip the spin of an electron in a magnetic field. if the magnetic field applied to the electrons is increased from 0.010 tesla to 0.011 tesla, how much. deltaf, will the transition frequency change? deltaf = 7 mhz deltaf = 14 mhz deltaf = 28 mhz
