ELECTROMAGNETIC WAVES: LIFE OR HARM B efore anything else let us know first what electromagnetic waves and Electromagnetic spectrum are? Light waves and other types of energy that radiate (travel out) from where they're produced are called electromagnetic radiation. Together, they make up what's known as the electromagnetic spectrum. The electromagnetic (EM) spectrum is the range of all types of EM radiation . Radio waves, microwaves , infrared , ultraviolet light , visible light, X-rays and gamma-rays are the types of EM waves that make up the electromagnetic spectrum. The electromagnetic spectrum from lowest energy/longest wavelength (at the top) to highest energy/shortest wavelength (at the bottom).
