Consider the electron of a Li2+ ion that undergoes a transition from a higher energy state n to its adjacent lower energy state n – 1 (e.g. n = 2→1, 3→2, 4→3, etc) and emits a photon. Suppose the emitted photon is used to strike the surface of potassium, which has a threshold frequency of 5.464 × 10^14 s–1.a) Whatisthemaximuminitialquantumnumber,n, that is required in order to emit a photon with high enough energy to generate a photocurrent from the metal surface?b) Usingthenvaluesolvedinpart(a), calculate the maximum speed of the photoelectron from potassium. If you couldn’t solve for n in part (a), use n = 3.
What would the wavelength in m of the emitted radiation be if a hydrogen atom was placed in an external uniform magnetic field of 240 T and transitioned from a spin-up to a spin-down state?
Consider a hydrogen atom in a large magnetic field.
Compute the wavelengths of the photons when it transitioned from the 2p → 1s levels when the hydrogen atom is placed in a magnetic field of 2.00 Tesla.
In total, consider the three transitions L=1 (2p) to L=0 (1s) associated with the three states ?ℓ= −1, 0, +1.
Draw the energy levels for B=0 T and B=2 T.
Ignore the effects of the intrinsic electron’s spin angular momentum and only consider the effect of the orbital angular moment L on the energy levels.
