A photon of blue light and a photon of red light are traveling in vacuum. The photon of blue light
 
  A) has a smaller wavelength than a photon of red light and travels with the same speed.
  B) has a smaller wavelength than a photon of red light and travels with a greater speed.
  C) has a longer wavelength than a photon of red light and travels with the same speed.
  D) has a longer wavelength than a photon of red light and travels with a greater speed.

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?
