Problem

Which of the following relations correctly expresses the stopping potential

V_0

of photoelectrons emitted from a metal surface in terms of the incident light frequency

\nu

and the work function

\phi

? a)

eV_0 = h\nu + \phi

eV_0 = h\nu - \phi

eV_0 = \phi - h\nu

eV_0 = \dfrac{h\nu - \phi}{2}
