Here's why:
* Electric and Magnetic Fields: Electromagnetic waves are characterized by oscillating electric and magnetic fields that are perpendicular to each other and to the direction of wave propagation. This means the fields are constantly changing in strength and direction as the wave travels.
* Self-Propagating: The changing electric field creates a changing magnetic field, and the changing magnetic field creates a changing electric field. This continuous cycle of interaction allows the wave to propagate through space without the need for a medium.
* Speed of Light: Electromagnetic waves travel at the speed of light in a vacuum, which is approximately 299,792,458 meters per second (m/s).
Examples of electromagnetic waves include:
* Radio waves
* Microwaves
* Infrared radiation
* Visible light
* Ultraviolet radiation
* X-rays
* Gamma rays
These waves differ in their frequencies and wavelengths, which determine their properties and uses.
