How is an electromagnetic wave produced?

Answer 1

electromagnetic waves are produced by the motion of electrically charged particles. electromagnetic waves are also called electromagnetic radiation because they radiate from electrically charged particles.

Answer 2

An electromagnetic wave is produced when an electric field and a magnetic field oscillate together perpendicular to each other. This oscillation creates a wave that propagates through space at the speed of light.

Answer 3

Electromagnetic energy is made when atoms absorb energy. This absorption causes a shift in the position of the electrons of the atom. When that electron returns to its original spot, a wave of energy is produced.

Answer 4

Electromagnetic waves are not produced, they exsist as part of the electromagnetic force (one of the four knows forces, like gravity), science still does not have an answer to how the four knows forces first began, this is one of the reasons for the large hadron collider, to try and find out how the universe came into exsistance.

Answer 5

electromagnetic waves are produced by the changes in the sub atomic level when heat or electricity is applied to an atom electron which is present in lower energy level will obsorbs energy and jumps in to higher energy level after that it again jumps in to lower energy level.when the electron is jumping in to lower energy level it emitts energy in the form of photons.these transmission of photons is said to be electromagnetic waves.in the electromagnetic waves electric and magnetic fields are perpendicular to each other and also perpendicular to the direction of wave propagation.

EM waves can also be produced by the action of a radio-frequency current in an antenna. Radio transmitters produce power at a single frequency and the antenna acts as a tranducer taking the power from the transmitter and converting it into power that is radiated into space and can be received at a distant point.

Answer 7

Electromagnetic waves vibrate through a medium.
