Help - energy of a photon :-/

[Yael]

Hi,
i have a question...

compute the shortest wavelength in each of these hydrogen spectral series: Lyman, Balmer, Paschen, and Brackett. (which i managed...)

my problem is with the second part of the question : compute the energy in electron volts of the highest energy photon produced in each series.

any suggestions? :-/

Thanks !

You have the wavelength, then you can calculate the frequency. After that you calculate the energy of the photons of each series. Then "translate" the energy into electron volts.

1 eV = 1.602x10^-19 J , i think this will help u to conver
