Determining ΔE and λ of an Electron Transition

  1. Nov 2, 2009 #1
    1. The problem statement, all variables and given/known data

    A hydrogen atom with its electron in the n = 6 energy level emits a photon of the infrared light. Calculate the change in energy of the atom and the wavelength of the photon.

    Using Rydberg's equation, the change in energy is 1.82 x 10^-19J

    But I do not understand why the change of energy is positive

    Wouldn't [tex]\Delta[/tex]E = -2.18 x 10^-18J (1/9 - 1/36) = -1.82 x 10^-19J ?

    What do you calculate using Rydberg's formula?

    Wavelength... let's make it energy of the emitted photon, OK?
