An electron is confined in a harmonic oscillator potential well.
 
  What is the longest wavelength of light that the electron can absorb if the net force on the electron behaves as though it has a spring constant of 74 N/m? (mel = 9.11  10-31 kg, c = 3.00  108 m/s, 1 eV = 1.60  10-19 J, h = 1.055  10-34 J  s, h = 6.626  10-34 J  s)
  A) 210 nm
  B) 200 nm
  C) 220 nm
  D) 230 nm

Question 2

Consider two cylinders of gas identical in all respects except that one contains oxygen O2 and the other helium He.
 
  Both cylinders initially contain the same volume of gas at 0C and 1 atm of pressure and are closed by a movable piston at one end. Both gases are now compressed adiabatically to one-third their original volume.
  (a) Which gas will show the greater temperature increase?
   A. the O2
   B) the He
   C) Neither; both will show the same increase.
   D) It is impossible to tell from the information given.
  (b) Which gas will show the greater pressure increase?
   A. the O2
   B) the He
   C) Neither; both will show the same increase.
   D) It is impossible to tell from the information given.
