a. Monochromatic light of frequency

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

and uniform intensity falls normally on two photocells A and B. The metals of A and B have threshold frequencies

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

and

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

respectively. (a) On a common set of axes, sketch the photocurrent versus applied potential curves for cells A and B. (b) On the same diagram, show qualitatively how both curves will change if the intensity of the incident light is doubled while keeping the frequency fixed. a. Monochromatic light of frequency
