🔍 Key Concepts

• Relationship between fundamental frequency and its harmonics (e.g., 2nd, 3rd, 4th) • How many complete sine-wave cycles fit into one cycle of the fundamental • Visual comparison of wavelength / frequency among A, B, C, and D in the diagram

💭 Think About

• Identify which labeled waveform is the fundamental (first harmonic) by finding the one with the slowest variation and longest wavelength • Count how many times each of the other labeled sine waves repeats within one full cycle of the fundamental • Match that count with the harmonic number (e.g., 2 cycles = 2nd harmonic, 3 cycles = 3rd harmonic, etc.)

✅ Before You Answer

• Be sure you are counting over exactly one full cycle of the fundamental waveform (from one identical point on the red wave to the next) • Confirm that the waveform you choose is a pure sinusoid, not the distorted resultant waveform at the bottom • Double-check that the waveform you select completes three full cycles in the same horizontal distance where the fundamental completes one.
