Maxwell's calculation showed that light is:
AA magnetic field line
BAn electromagnetic wave
CA stream of hot air
DA displacement current
Answer & Solution
Correct answer: B. An electromagnetic wave
1. The predicted wave speed equalled the measured speed of light.
2. That match could not be a coincidence.
3. So light itself is an electromagnetic wave.
