Question:medium
State any three characteristics of electromagnetic waves.
State any three characteristics of electromagnetic waves.
Show Hint
Displacement current is not a real current of moving charges; it accounts for the changing electric field in regions like the gap between capacitor plates and ensures current continuity in Maxwell's equations.

Solution and Explanation
Electromagnetic Wave Properties:
- Electromagnetic (EM) waves are transverse waves. They consist of oscillating electric and magnetic fields that are mutually perpendicular to each other and to the direction of propagation.
- Electromagnetic waves do not require a material medium for propagation and can travel through a vacuum.
- In a vacuum, electromagnetic waves propagate with a constant speed denoted by c, equal to \( 3 \times 10^8 \, \text{m/s} \).
