An electromagnetic wave is propagating along Y-axis. Then:
Correct answer: B. Oscillating electric field is along Z-axis and oscillating magnetic field is along X-axis
- A. Oscillating electric field is along X-axis and oscillating magnetic field is along Y-axis
- B. Oscillating electric field is along Z-axis and oscillating magnetic field is along X-axis
- C. Both oscillating electric and magnetic fields are along Y-axis, but phase difference between them is 90°
- D. Both oscillating electric and magnetic fields are mutually perpendicular in arbitrary directions
Explanation
An electromagnetic wave is propagating along Y-axis, then oscillating electric field is along Z-axis and oscillating magnetic field is along X-axis.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
