Sketch the graphs, showing the variation of stopping potential `V_s` with frequency v of the incident radiations for two photosensitive materials A and B having threshold frequencies `v_0gtv'_0` respectively.
(i) which of the two metals A or B has higher work function?
(ii) What information do you get from the slope of the graphs?
(iii) What does the value of the intercept of graph A on the potential axis represent?

Explanation

To solve the problem step by step, we will sketch the graphs and analyze the information provided.

### Step 1: Sketch the Graphs
1. **Draw the axes**:
- The x-axis represents the frequency (ν) of the incident radiation.
- The y-axis represents the stopping potential (Vs).

2. **Identify the threshold frequencies**:
