ELECTROMAGNETIC RADIATION Meaning and
Definition
-
Electromagnetic radiation refers to the phenomenon of energy propagation through space in the form of electromagnetic waves. These waves consist of electric and magnetic fields oscillating perpendicularly to each other and also perpendicular to the direction in which they are traveling. They are composed of packets of energy called photons.
Electromagnetic radiation encompasses a wide range of frequencies, from extremely low frequencies (ELF) to extremely high frequencies (EHF), which are commonly referred to as the electromagnetic spectrum. This spectrum includes different types of radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
This natural or artificial radiation can travel through a vacuum or any medium with varying speeds depending on the material. Each type of radiation within the electromagnetic spectrum possesses its own distinct properties, behaviors, and interactions with matter.
Electromagnetic radiation is fundamental to many aspects of science and technology. From its applications in telecommunications (radio and television broadcasting) and medical imaging (X-ray and magnetic resonance imaging) to its importance in astronomy and the study of the universe, electromagnetic radiation has proven to be of immense value for understanding and manipulating the physical world.
However, it is important to note that certain forms of electromagnetic radiation, such as X-rays and gamma rays, can be potentially harmful to living organisms in high doses, and precautions should be taken to limit exposure to these types of radiation.

Etymology of ELECTROMAGNETIC RADIATION
The term "electromagnetic radiation" has its etymology rooted in the Greek and Latin languages.
The word "electromagnetic" combines the Greek words "ēlektron" meaning "amber" and "magnos" meaning "great". The Greek term "ēlektron" refers to a naturally occurring substance, amber, which when rubbed, creates static electricity. "Magnos" conveys the idea of something large or great. Thus, "electromagnetic" can be understood as "pertaining to the large force of electricity".
The word "radiation" comes from the Latin word "radiare" which means "to emit rays or beams". It is derived from the Latin word "radius" meaning "ray" or "spoke of a wheel". Hence, "radiation" refers to the emission of energy in the form of rays or waves.
