(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

For an incoming light shining on a metal surface, I am given the wavelength, the cutoff voltage, the frequency (by using f = c/w). From here, Im having trouble finding the maximun Ek of the ejected electrons in electron volts (eV) and joules (J).

2. Relevant equations

Ek max = eV

E = hƒ = hc / λ

Ek max = E (photon) - work

3. The attempt at a solution

Im guessing that i can use the equation Ek max = eV by substituting in the cutoff voltage and the charge on an electron to get the Ek max in joules, but then how do I get it in electron volts? Is there a conversion factor, or another equation I use??

PLz help..
