The minimum frequency of light needed to eject electrons from a metal is called the threshold frequency, ν0. Find the minimum energy needed to eject electrons from a metal with a threshold frequency of 5.48 × 1014 s–1.
With what kinetic energy will electrons be ejected when this metal is exposed to light with a wavelength of λ = 225 nm?
For the first half I got 3.63*10^(-19)
and that was correct. I just can't get the second part.
