What else can I help you with?
What is the phase relation between oscillating electric and oscillating magnetic fields in an electromagnetic wave?
The fields are in time phase and space quadrature.
Why do polar molecules absorb IR?
You can view incident IR radiation as an oscillating electric field ( the 'wave-like' view of EM radiation.) As such, it effects the vibration of a molecule by inducing a dipole oscillation of the same frequency. The connection is most clearly seen if you consider that the induced dipole oscillation produces an identical oscillating electric field to the field that induced it. A molecule can only produce an oscillating electric field by vibration if its vibration produces a change in dipole moment (a non-polar molecule would produce a constant electric field regardless of the vibration.) I hope that helps
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 electromagnetic waves get their name?
Electromagnetic waves get their name because they are composed of oscillating electric and magnetic fields that propagate through space. These waves are characterized by their dual nature, with electric and magnetic components perpendicular to each other and to the direction of propagation.
If electro magnetic waves are produced by motion of electrically charged particles then how could they travel in vaccume?
good question, unfortunately nobody really knows! Initially, scientists assumed it was travelling through some undetected medium which they called the ether. But no one managed to prove it. Now scientists just say that it is a self-propagating wave of oscillating electric and magnetic fields, so it doesnt need a medium to travel through.
What causes electromagentic waves?
Oscillating electric charges.
What is the phase relation between oscillating electric and oscillating magnetic fields in an electromagnetic wave?
The fields are in time phase and space quadrature.
Which toothbrushes have an oscillating head?
There are various companies that sell electric or battery operated toothbrushes also have oscillating heads. Some of the brands that have toothbrushes with an oscillating head are Oral B, Philips and Arm and Hammer.
Phase relationship between oscillating electric and magnetic fields?
nothing
What is the difference between s polarized and p polarized light?
S polarized light has its electric field oscillating perpendicular to the plane of incidence, while p polarized light has its electric field oscillating parallel to the plane of incidence.
What object is electromagnetic?
Light is an electromagnetic wave that consists of oscillating electric and magnetic 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.
Why do you describe light as electromagnetic radiation?
because light is made up of oscillating electric and magnetic fields
What must happen in order for an electromagnetic wave to form?
An electromagnetic wave is formed when an oscillating electric field creates an oscillating magnetic field, and vice versa. When these two fields interact and propagate through space, they form an electromagnetic wave.
How can electromagnetic waves be produced?
Any electric charge undergoing acceleration will produce Electromagnetic waves. This is by far the most common way.If an oscillating electric field is synchronized with an oscillating magnetic field of exactly the same frequency a beam of light will be produce where the two fields are orthogonal in all dimensions.
How do oscillating electric fields affect the behavior of charged particles in a vacuum?
Oscillating electric fields cause charged particles in a vacuum to move back and forth rapidly, leading to acceleration and emission of electromagnetic radiation. This phenomenon is known as synchrotron radiation and is commonly observed in particle accelerators and astrophysical environments.
What is the kind of wave formed by an electric fields and a magnetic fields oscillating at right angles to each other?
Electromagnetic wave.
