What is the maximum velocity of a photoelectron emitted from a surface with work function 5.22 eV when illuminated by 200-nm ultraviolet light? (melectron = 9.11  10-31 kg, h = 6.63  10-34 Js, 1 eV = 1.60  10-19 J, and 1 nm = 10-9 m)
 a. 800,000 m/s
  c. 653,000 m/s
  b. 212,000 m/s
  d. 591,000 m/s

How much energy (in eV) does a photon of 500-nm light have? (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. 1.78 eV
  c. 1.24 eV
  b. 2.48 eV
