The stopping potential as a function of the frequency of the incident radiation is plotted for two different photoelectric surfaces \(A\) and \(B\). The graphs demonstrate that \(A\)'s work function is:

           

1. Greater than that of \(B\). 2. Smaller than that of \(B\).
3. Equal to that of \(B\). 4. No inference can be drawn about their work functions from the given graphs.
