### Solving for work frequency

I know the work frequency equation is threshold frequency times the plancs constant. I was wondering if solving the threshold frequency equation is E=hv. Then you multiply it with the plancs constant in order to get the work function?

### Re: Solving for work frequency

The work function is the minimum amount of energy of a light needed to remove electrons. Therefore, since the work function is essentially also a light, the equation E=hv, which is used for energy of a light, can also be used to relate the frequency and energy of a work function.

Hope this helps!
