The electric and magnetic fields of an electromagnetic wave are:

Question

Accepted Answer

1. **Perpendicular Orientation:** Electromagnetic waves consist of oscillating electric and magnetic fields. These fields are perpendicular to each other and both are perpendicular to the direction of propagation of the wave .
2. **Phase Relationship:** As illustrated in standard depictions of electromagnetic waves (e.g., Fig 2.6 in the source), the electric and magnetic field components oscillate in phase. This means they reach their maximum and minimum values at the same instants in time and at the same points in space .
