Electromagnetic radiation encompasses a broad spectrum of energy that includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. These waves propagate through space in the form of oscillating electric and magnetic fields, carrying energy and information. The importance of electromagnetic radiation is profound and multifaceted, influencing various aspects of our daily lives and scientific advancements. It plays very crucial role in communication and technology, information technology, medical applications, remote sensing, energy production, security and defence etc. While electromagnetic radiation serves numerous beneficial purposes, certain types and levels of exposure can have harmful effects on living organisms. It's crucial to recognize potential risks associated with prolonged or intense exposure to electromagnetic radiation. It is important to note that the potential harm associated with electromagnetic radiation depends on factors such as the type of radiation, intensity, duration of exposure, and individual susceptibility.
