Electromagnetic wave
Electromagnetic Wave
An Electromagnetic Wave (pronunciation: /ɪˌlɛktrəʊmæɡˈnɛtɪk weɪv/) is a type of wave that is propagated by the Electromagnetic field.
Etymology
The term "Electromagnetic Wave" is derived from the words "electro", referring to electricity, and "magnetic", referring to the magnetic properties of the wave. The term "wave" is used to describe the oscillating nature of the phenomenon.
Definition
Electromagnetic Waves are waves that can travel through the vacuum of outer space. They are generated by the vibration of electrically charged particles, and can be described in terms of a combination of electric fields and magnetic fields.
Properties
Electromagnetic Waves have certain properties that distinguish them from other types of waves. These include their speed, which is the speed of light, their ability to travel through a vacuum, and their transverse nature. They also exhibit properties of both wave-particle duality, showing characteristics of both particles and waves.
Types
There are several types of Electromagnetic Waves, including radio waves, microwaves, infrared waves, visible light, ultraviolet rays, x-rays, and gamma rays. Each type has a different wavelength and frequency, and is used in different applications.
