The variation of stopping potential ( $V_0$ ) as a function of the frequency ( $v$ ) of the incident light for a metal is shown in the figure. The work function of the surface is:

Graph of stopping potential V0 in volt versus frequency v in units of 10^14 Hz, showing a straight line starting near 5 × 10^14 Hz at zero stopping potential and rising to about 2.5 V near 10 × 10^14 Hz.

A
