- Radio and Television. Radio Waves are typically used for the purpose of signal broadcasting via various signal modulation techniques such as frequency modulation, amplitude modulation, etc.
- Microwave Ovens. As the name signifies, microwave ovens make use of high energy possessed by the microwaves to cook or heat the food. The frequency range of microwaves lies between 1 GHz to 1000 GHz.
- Medical Examination. A number of electromagnetic waves are used for medical diagnosis purpose. For instance, X-Rays are used to get an image of tissues and bones, thereby allowing the medical examiner to locate broken bones or injured body tissues.
- Sterilization. The electromagnetic rays lying in the wavelength range of 80 nanometers to about 10 nanometers are known as UV rays or ultraviolet rays.
Some common forms of electromagnetic radiation include microwaves, television waves, radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. Each form has different wavelengths and energy levels, resulting in unique properties and applications.

May 21, 2024 · Electromagnetic radiation is a term used to describe a stream of energy-bearing particles that travels outward from an electromagnetic source. The energy in these streams can vary extensively in power, and is measured by the electromagnetic spectrum.
Mar 13, 2020 · Electromagnetic (EM) waves, also called electromagnetic radiation, are created by the coupling of oscillating electric and magnetic fields, whose directions are perpendicular to each other. The direction of propagation of the EM wave is perpendicular to both the electric and magnetic field vectors.
Dec 28, 2020 · Electromagnetic radiation is formed from the intersection of a magnetic field and an electric field oriented perpendicularly to each other. The EM wave propagates transversely to both. Visible light lies between 400 and 700 nm, but it is a tiny fraction of the EM spectrum overall.
