How to Compute Highest Energy Photon in Hydrogen Spectral Series?

[Yael]

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).
