What starts the vibration of the electric and magnetic fields in an electromagnetic wave?
The vibration of the electric and magnetic fields in an electromagnetic wave is initiated by a changing electric current or an accelerating electric charge. When these occur, the varying electric and magnetic fields interact and propagate through space in the form of an electromagnetic wave.
What else can I help you with?
How are the magnetic fields oriented in relation to the electric fields in electromagnetic waves?
In electromagnetic waves, the magnetic fields are oriented perpendicular to the electric fields.
What causes a electromagnetic wave?
An electromagnetic wave is caused by the vibration of electric and magnetic fields propagating through space. When an electric charge accelerates, it creates a changing electric field, which in turn generates a magnetic field. The changing magnetic field then creates a changing electric field, and this cyclical process results in the formation of an electromagnetic wave.
What is the difference between magnetic and electromagnetic fields?
Magnetic fields are created by permanent magnets or electric currents, while electromagnetic fields are created by electric currents. Electromagnetic fields are more complex and can change over time, while magnetic fields are static.
What causes electromagnetic waves?
Electromagnetic waves are caused by the vibration of electric charges. When an electric charge is accelerated or decelerated, it creates changing electric and magnetic fields that propagate through space as electromagnetic waves.
What is the difference between electromagnetic and magnetic fields?
Electromagnetic fields are a combination of electric and magnetic fields that oscillate and propagate through space, carrying energy. Magnetic fields, on the other hand, are produced by moving electric charges and exert forces on other moving charges. In summary, electromagnetic fields involve both electric and magnetic components, while magnetic fields are solely produced by moving electric charges.
How are the magnetic fields oriented in relation to the electric fields in electromagnetic waves?
In electromagnetic waves, the magnetic fields are oriented perpendicular to the electric fields.
In an electromagnetic wave the oscillating electric and magnetic fields are what?
In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other and are in phase.

In an electromagnetic wave, in what direction do the electric and magnetic fields point towards each other?
In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other.
When and magnetic fields both exist it is called an electromagnetic field.?
Yes, an electromagnetic field refers to the combination of electric and magnetic fields that are generated by electric charges and changing magnetic fields. This field propagates through space and carries electromagnetic energy.
What type of wave is EM radiation?

It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.
Are electromagnetic waves deflected by magnetic and electric fields?
According to photon theory ,electromagnetic radiation consists of photon which are changeless particles. therefore they are not deflected by electric or magnetic fields.
What is light an oscillation of?
Light is an electromagnetic wave, that is, an oscillation of both the electric and the magnetic fields.
Does the direction of the electromagnetic wave propagation same as the direction of vibration of electromagnetic waves?
No, the direction of electromagnetic wave propagation is perpendicular to the direction of vibration of the electric and magnetic fields that make up the wave. This relationship is governed by electromagnetic wave theory and is a fundamental characteristic of how electromagnetic waves travel through space.
