The EM waves are mainly used for wireless communications in EE. Examples include FM radio, cellular network in mobile, TV, satellite communications, wireless remote controls, etc.

EM waves is used as a means to transmit information in the form of electrical and magnetic diturbances in the air through distances. Without EM waves in EE applications, signal processing and communications would not be so easy.

Do you wish to know what kinds of things undergo oscillitory motion?
 

What are electromagnetic waves?

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.

What is the importance of electromagnetic waves in electrical engineering?

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.

What are some common uses of electromagnetic waves in electrical engineering?

Some common uses of electromagnetic waves in electrical engineering include radio and television broadcasting, cellular communication, radar systems, MRI machines, and microwave ovens.

How are electromagnetic waves generated?

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.

How do electromagnetic waves differ from other types of waves?

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.
