I am having trouble identifying a metal (based on its work function) given the wavelength and stopping potential. I will give more specifics below but can anyone help me with useful formulas to make this a little more streamlined in the future? Thanks!

Ultraviolet radiation with wavelength 200.0 nm hits a metal and electrons are emitted, which can be stopped by a potential of 3.33 V. What is the work function/identity of the metal?
