Homework Help: Help - energy of a photon

  1. Mar 26, 2006 #1
    hi,

    i have a question...
    i was asked to compute the shortest wavelength in each of these hydrogen spectral series: Lyman, Balmer, Paschen and Bracket - which i did...

    in the second part i need to compute the energy (in electron volts) of the highest energy photon produced in each series.

    my problem is with the second part...

    can anyone please help ?

    Interesting, I would expect the second part to come first.

    The highest energy photon has the shortest wavelength; you're being asked for the same photons. You need the relationship between wavelength and energy (featuring Plank's constant).
