The graph between variation of stopping potential and frequency is shown is Fig.

Since work function W = hv0
Let W1 be work function of photosensitive material A and W2 is that of B, then the threshold frequency for material A will be greater than that of B.
The slope of the line = \(\frac{V}{\lambda}\) i.e. the slope of the line is ratio of stopping potential and frequency which is constant for all metals. The intercept of the line depends upon the threshold frequency and larger the work function, more will be the threshold frequency.
