What does Electromagnetic energy travel in?
It flows through the system and then moves to the left and pi= 3.14 then a dog eats your homework. Whoever reads this is smart.... eyeamawetard!
As an electromagnetic wave travels its energy is carried through?
constantly changing electric and magnetic fields.
An electromagnetic wave carries electric and magnetic energy that travels at the speed of 300000000 meters per what?
per second
When electromagnetic energy travels from air into water the waves are bent due to the density differences between the air and water what is this bending called?
That is called "refraction".
What is the propagating wave in space with electric and magnetic components?
That is called an electromagnetic wave. Electromagnetic waves include visible light, infrared, ultraviolet, x-rays, gamma rays, and radio waves. If both the electric and the magnetic components are standstill (do not move) there will be no propagating waves. The wave will be created if either the electric or the magnetic moves or disturbed. The electromagnetic wave will spread out everywhere on the plane with a frequency perpendicular to its direction. In vacuum, the wave travels at the speed of light. In other mediums, the speed will be less than the speed of light. The wave will spread out uniformly an all direction if the density if the medium in uniform.
Which type of energy travels as alternating electric and magnetic fields?
Electromagnetic energy.
Which type of energy travels in waves?
An electromagnetic wave, such as light.An electromagnetic wave, such as light.An electromagnetic wave, such as light.An electromagnetic wave, such as light.

What does Electromagnetic energy travels?
Electromagnetic energy travels in waves.
An electromagnetic wave carries electric and magnetic energy that travels at the speed of 300000000 meters per what?
per second
What is the source of electromagnetic wave?
Electromagnetic waves come from accelerating electric charges, often electrons in atoms. The energy given off travels in a wave that is partly electric and partly magnetic.
How long does earths magnetic flip take?
An electromagnetic wave is a form of radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge. An electromagnetic wave travels like any other form of radiation or light, except for the fact that an electromagnetic wave moves perpendicular to an electric field and a magnetic field.
What kind of Wave is an electromagnetic wave how fast does it travel?
An electromagnetic wave is a wave with electric component and magnetic component. In free space (vacuum), an electromagnetic wave travels with the speed of light, that is 3x10^8 m/s. In fact, light is also an electromagnetic wave.
When electromagnetic energy travels from air into water the waves are bent due to the density differences between the air and water what is this bending called?
That is called "refraction".
What radiation waves does an electric radio produce?
The radio receptor receives electromagnetic waves from a broadcast station.These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.
What is the source of all electromagnet waves?
Electromagnetic waves come from accelerating electric charges, often electrons in atoms. The energy given off travels in a wave that is partly electric and partly magnetic.
