electromagnetic radiation
Energy traveling wavelike
Electromagnetic radiation is energy that travels through space as waves of electric and magnetic fields—light, radio waves, X-rays, microwaves, and gamma rays are all forms.
The spectrum ranges from low-frequency radio waves to high-frequency gamma radiation, with visible light occupying a narrow band in between.
The doctor ordered imaging that uses electromagnetic radiation to see inside the body.
