Here's why:
* Electromagnetism: Electromagnetic waves are a result of the interaction between electric and magnetic fields. These fields oscillate perpendicular to each other and to the direction the wave travels.
* Speed of Light: The speed at which these waves propagate is a fundamental constant of the universe, known as the speed of light (approximately 299,792,458 meters per second).
Examples of electromagnetic waves include:
* Radio waves: Used in communication, broadcasting, and radar.
* Microwaves: Used in cooking, communications, and radar.
* Infrared radiation: Used in heat sensing, night vision, and remote controls.
* Visible light: The portion of the electromagnetic spectrum that our eyes can see.
* Ultraviolet radiation: Can cause sunburns and is used in sterilization.
* X-rays: Used in medical imaging and industrial applications.
* Gamma rays: Highly energetic radiation emitted by radioactive materials.
