Structure of Atom: in class practice excises, October 19, 2014

hint:  go to Princeton Review AP Chemistry book, page 275 to find the equation and the constant

  1. What are the frequency of and energy of blue light that has wavelength, λ, of 400.0 nm?
  2. What are the wavelength, λ, and the energy of light that has a frequency of 1.50 X 1015 S-1?
  3. Determine the energy and wavelength of light associated with an electron moving from the second (n = 2) to the fourth (n = 4) energy level in a hydrogen atom.
