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.
What emit radiation?
anything hotter than absolute zero temperature
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
Is light two dimensional?
Actually, it has three dimensions. Two directions along oscillating magnetic and electric field vectors and one direction along the wave propagation.
When electrons are rearranged in an object by an electric field the object is charged by what?
electron rearrangement is caused by the force exerted on the electrons by the oscillating charges of the field. so in a way the rearrangement is caused by the charges of the field
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 are three parts of a wavelength?
There is one part to a wavelength - the wavelength, measured in metres.
Electrical energy to mecanical energy?
they are produced by the vibration of oscillating electric and magnetic fields
What creates waves?
Oscillating charges. (Electric current that goes back and forth periodically.)
What emit radiation?
anything hotter than absolute zero temperature
Why do you describe light as electromagnetic radiation?
because light is made up 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.
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.
What is the kind of wave formed by an electric fields and a magnetic fields oscillating at right angles to each other?
Electromagnetic wave.
