An electron is trapped in an infinite square well (a box) of width Find the wavelength of photons emitted when the electron drops from the n = 5 state to the n = 1 state in this system.
 
  (c = 3.00  108 m/s, h = 6.626  10-34 J  s, mel = 9.11  10-31 kg)
  A) 6.49 m
  B) 5.45 m
  C) 5.91 m
  D) 7.07 m

Question 2

An electron in an infinite potential well (a box) makes a transition from the n = 3 level to the ground state and in so doing emits a photon of wavelength 20.9 nm. (c = 3.00  108 m/s, h = 6.626  10-34J  s, mel = 9.11  10-31 kg)
 
  (a) What is the width of this well?
  (b) What wavelength photon would be required to excite the electron from its original level to the next higher one?
  What will be an ideal response?
