🔍 Key Concepts

• Compare the relative position of the BUS and Incoming Machine sine waves as they move left to right (phase angle axis). • Think about what it means if one waveform’s peaks and zero-crossings are catching up to or falling behind the other – that’s a clue to frequency difference. • Remember that voltage magnitude is shown by the height of the wave, while frequency is shown by how many cycles fit into the same horizontal distance.

💭 Think About

• As you follow the waves from left to right, is the Incoming Machine wave moving ahead of the BUS wave, or is it dropping behind it? What does that say about its frequency compared to the bus? • At the point labeled "Waves in Synchronism," the peaks line up. Looking to the left of that point, which wave had to "travel farther" to become aligned? • Do the amplitudes (heights) of the two waves look significantly different, or are they mainly offset in time/phase? How does that affect which choices you can immediately rule out?

✅ Before You Answer

• Verify which waveform represents the BUS and which represents the Incoming Machine (use the labels on the graph). • Check whether there are more or fewer complete cycles of the Incoming Machine wave compared to the BUS over the same phase-angle span. • Confirm whether the question is asking about frequency or voltage before deciding which statements can be eliminated.
