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

(b)

eV_0 = h\nu - \phi

(c)

eV_0 = \phi - h\nu

(d)

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