Do electromagnetic waves consist of changing electric and changing magnetic?
Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. Also note that electric and magnetic fields in an EM wave are also perpendicular to each other.

What do electromagnetic wave consist of?
Definition of ‘Electromagnetic Waves’ Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.
How are mechanical waves and electromagnetic waves different?
These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
What is the frequency of the electric field?
0 Hz
Characteristics of the field and its use Hence, static electric fields have a frequency of 0 Hz. They exert a force on charges or charged particles.
What is electromagnetic wave frequency?
Frequency is the number of waves that form in a given length of time. It is usually measured as the number of wave cycles per second, or hertz (Hz). A short wavelength means that the frequency will be higher because one cycle can pass in a shorter amount of time, according to the University of Wisconsin.
What is electromagnetic wave and mechanical wave?
An electromagnetic wave is a wave that is capable of transmitting its energy through a vacuum (i.e., empty space). Electromagnetic waves are produced by the vibration of charged particles. A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum.
How are electric and magnetic waves related to each other?
Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase. The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.
How does an EM wave propagate in the electromagnetic field?
Electromagnetic waves the EM wave propagates because the electric field recreates the magnetic field and the magnetic field recreates the electric field an oscillating voltage applied to the antenna makes the charges in the antenna vibrate up and down sending out a synchronized pattern of electric and magnetic fields
How does the creation of an electromagnetic wave occur?
The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields. Once in motion, the electric and magnetic fields that a charged particle creates are self-perpetuating: time-dependent changes in one field (electric or magnetic) produce the other.
Is the electromagnetic wave a transverse or transverse wave?
The electromagnetic wave is therefore a transverse wave, with its oscillating electric and magnetic fields perpendicular to its direction of propagation.
