The diagram shows the trace produced on the screen of an oscilloscope due to an alternating voltage input. The time-base on the oscilloscope is set to 4 ms/cm. What does the trace look like when the time base is set to 2 ms/cm?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

AOscilloscope trace A (showing 3 full cycles within the same width as the original)

BOscilloscope trace B (showing 1.5 full cycles within the same width as the original)

COscilloscope trace C (showing 4 full cycles within the same width as the original)

DOscilloscope trace D (showing 2 full cycles within the same width as the original)

✓ Correct answer

C: Oscilloscope trace C (showing 4 full cycles within the same width as the original)
