What are the Electromagnetic Waves used for in Electrical Engineering?
Very much also for regular AC transmission through wires and waveguides.cyeokpeng said:The EM waves are mainly used for wireless communications in EE.
Electromagnetic waves are a type of energy that is created by the movement of electrically charged particles. They consist of electric and magnetic fields that oscillate in perpendicular directions and travel through space at the speed of light.
Electromagnetic waves are essential in electrical engineering as they are used for communication, energy transmission, and medical imaging. They allow for the transfer of information and energy over long distances without the need for physical wires or connections.
Some common uses of electromagnetic waves in electrical engineering include radio and television broadcasting, cellular communication, radar systems, MRI machines, and microwave ovens.
Electromagnetic waves are generated when an electric charge is accelerated or decelerated. This can occur naturally, such as in lightning strikes, or through man-made devices like antennas and generators.
Electromagnetic waves are different from other types of waves because they do not require a medium to travel through. This means that they can travel through a vacuum, unlike mechanical waves. They also have a wide range of frequencies, from extremely low radio waves to high-energy gamma rays, whereas other types of waves have a more limited range.
