Question 3
The output potential difference (pd) of the signal generator is displayed on the oscilloscope, as shown in Figure 16. The time-base setting of the oscilloscope is 1... show full transcript

Answer
To find the frequency , we first need to measure the time period of one complete cycle from the oscilloscope display. The horizontal scale shows that 1 cm represents 10 ms. From the graph, we can identify that one complete wave spans across several divisions.
Assuming one complete wave corresponds to, for example, 5 cm:
Using the formula for frequency:
