Homework Help: General Chemistry

Posted by Kat on Sunday, January 13, 2008 at 4:54am.

The photogenic work function of a metal is the minimum energy needed to eject an electron by irradiating the metal with light. For calcium, this work function equals 4.34 x 10^-19 J. What is the minimum frequency of light for the photoelectric effect in calcium?

I'm confused so if you could break it down how you got the solution I will greatly appreciate it. Thanks again.
