Homework Help: General Chemistry

Posted by Emily on Wednesday, October 3, 2012 at 8:40pm.

What is the velocity of an electron ejected, if any, from a piece of metal whose work function is 2.227 x 10^-19 J when a photon whose wavelength is 319 nm hits the metal in a vacuum?


I know the answer is 9.372 x 10^5 m/s, but I am not entirely sure of how to get to this answer. Thank you!
