How is an electromagnet wave generated?
We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.
Why is a vibrating electric field an example of an electromagnetic wave?
A vibrating electric field produces a changing magnetic field, which then generates a changing electric field and so on, creating a self-propagating wave. This wave consists of oscillating electric and magnetic fields perpendicular to each other and to the direction of wave propagation, thus exhibiting the characteristics of an electromagnetic wave.
Why an electromagnetic wave is able to produce both an electric field and a magnetic field because?
The question founders on the rocks of a chicken/egg conundrum. The presence of both an electric field and a magnetic field is required in order to produce an electromagnetic wave.
How does a vibrating electric charge produce an electromagnetic wave?
When an electric charge vibrates, it creates changing electric and magnetic fields. These changing fields propagate through space, creating electromagnetic waves. The oscillating electric field produces a magnetic field, and the changing magnetic field then produces an electric field, thus creating a self-sustaining wave.
A wave that consists of changing electric and magnetic fields is called?
Magnetic field
What changes a sound wave into an electric current?
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
What does electromagnetic waves means?
An electromagnetic wave, in its simplest description, is a wave that as it propagates keeps converting its magnetic field into an electric field while converting its electric field into a magnetic field.
What are the two components of light wave?
The electric and the magnetic field components.
Is the sound from an electric guitar a sound or electromagnetic wave?
sound waves are all around us. the electric guitar will make/reflect sound waves just as it sits in the corner. sound waves is what sound is only that sound waves is the more scientific way of saying it.
Is it necessary whenever there is an electric field there will be a magnetic field in perpendicular direction thus producing em waves if not what is the condition of em wave generation?
A moving charge (such as an electrical current) generates a magnetic field at right angles, true, but this field is stable and unchanging. An EM wave is only produced by a changing movement, for example an AC current. The condition would be that the field will change (and produce a wave) only if the current changes.
Is sunshine a mechanical wave?
No, it is an electromagnetic wave containing electric field component and a magnetic field component.
What is a wave that consists of changing electric and magnetic fields called?
Sound wave
