Problem

The stopping potential for a certain metal is

0.70\,\text{V}

when it is irradiated with light of frequency

6.5\times10^{14}\,\text{Hz}

. If the slope of the

V_0\! - \!\nu

graph for this metal is

4.14\times10^{-15}\,\text{V\,s}

, predict the approximate stopping potential when the same metal is illuminated with light of frequency

8.0\times10^{14}\,\text{Hz}

. Show the point you have obtained on a qualitative

V_0\! - \!\nu

sketch.
