Which of the following statements about electromagnetic waves is correct?

Electromagnetic waves are characterized by the presence of both electric and magnetic fields oscillating perpendicular to each other and to the direction of wave propagation. This fundamental aspect is a defining feature of electromagnetic radiation, which includes visible light, radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. The electric and magnetic fields regenerate each other as the wave travels, allowing electromagnetic waves to propagate through a vacuum as well as through various media. The ability of electromagnetic waves to carry energy without needing a medium distinguishes them from mechanical waves, such as sound waves, which require a substance to travel through. Therefore, stating that they have both electric and magnetic fields accurately describes their nature and behavior in different environments.
