A photon is emitted from a hydrogen atom that undergoes a transition from n = 3 to n = 2 . Calculate the energy and wavelength of the photon. (The ionization energy of hydrogen is 13.6 eV, and h = 6.63  10-34 Js, c = 3.00  108 m/s, 1 eV = 1.60  10-19 J, and 1 nm = 10-9 m)
 a. 2.21 eV, 563 nm
  c. 2.58  1019 J, 658 nm
  b. 1.89 eV, 460 nm
  d. 3.02  1019 J, 658 nm

Question 2

A hydrogen atom in the ground state absorbs a 12.75-eV photon. To what level is the electron promoted? (The ionization energy of hydrogen is 13.6 eV).
 a. n = 2
  c. n = 5
  b. n = 3
  d. n = 4
