Homework Statement



What is the frequency of a photon of energy 58eV?

Homework Equations



E=hF

where H is Planck's constant, 6.63x10^-34



The Attempt at a Solution



58/ (6.63x10^-34) = 8.75e34

that is not correct.

Do i have the energy eV into a certain unit?

When in doubt, put everything in units of MKS (meters, seconds, and kg).

MKS energy unit is the Joule = kg * m^2 / s^2
