What does horizontal wave polarization mean?
- A The electric lines of force of a radio wave are parallel to the Earth's surface
- B The electric and magnetic lines of force of a radio wave are perpendicular to the Earth's surface
- C The electric lines of force of a radio wave are perpendicular to the Earth's surface
- D The magnetic lines of force of a radio wave are parallel to the Earth's surface
Correct answer: A — The electric lines of force of a radio wave are parallel to the Earth's surface. From the official ISED question bank, verified word for word.
Why
Radio waves are described by their electric field, which consists of invisible lines of force. The full explanation — and one for every question — is in Pro.
