Electromagnetic Waves
Electromagnetic waves are forms of energy that propagate through space as interconnected electric and magnetic fields, traveling at the speed of light. They span a vast spectrum from low-frequency radio waves to high-energy gamma rays, enabling everything from wireless communication to medical imaging, and have revolutionized how we interact with the world in the digital age.
Did you know?
All electromagnetic waves, no matter their wavelength—from the radio signals we use for FM broadcasts to the X-rays that peer inside our bodies—travel at exactly the same speed in a vacuum: 299,792 kilometers per second, a constant that underpins Einstein's theory of relativity and makes space communication possible across vast distances.
