Find the kinetic energy of these photoelectrons

Reference no: EM13264678

A sample of hydrogen atoms is irradiated with light of wavelength 50 nm, which causes photoelectrons to be emitted. If each hydrogen atom is originally in its n=2 level, what is the kinetic energy (in electron volts) of these photoelectrons?
