What will be the effect on the motion of electron if it travels along the dirction of electric field?
The "direction" of the electric field is defined as the direction of the force it exerts on a small positive charge. The direction of the force on an electron in the field is exactly opposite to the direction of the field, and its effect is to accelerate the electron in the direction of the force.
Can an electric current generate an electromagnetic wave?
Not a constant electric current but a changing one will generate electromagnetic waves.First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.
When electric and magnetic fields both exist it is called an?
Not really. You could have both an electric field and a magnetic field occupying the same space at the same time but they wouldn't 'make the definition' of electromagnetic until they began to fluxuate in phase at a harmonized frequency.
What happens to the potential energy of a stationary charge when it begins to move freely from one point to another under the influence of an electric field?
The potential energy of the particle goes down just as its kinetic energy, which results from the particle's increasing motion, increases - thereby conserving the total energy of the system. Of course these terms refer ONLY to the potential energy due to the charged particle's presence in an electric field and its change in motion in the direction of that field. If there were also a gravitational field present and the particle had mass, it would have also have potential (and kinetic, if it's falling too) energy from that field, independently of the electric field.
Photon does not have charge then how does it have electromagnetic field?
Well one way to look at it is that a photon IS an electromagnetic field. The photon is the gauge particle for the electromagnetic force. Without photons there would be no electromagnetic interaction force, and therefore no electromagnetic fields.
What is an electron transition?
The electric dipole transition refers to the dominant?æeffect of the atom's electron interaction in the electromagnetic field. It is also the transition between the system energy levels with?æthe Hamiltonian.
What will be the effect on the motion of electron if it travels along the dirction of electric field?
The "direction" of the electric field is defined as the direction of the force it exerts on a small positive charge. The direction of the force on an electron in the field is exactly opposite to the direction of the field, and its effect is to accelerate the electron in the direction of the force.
What is Compton effect?
The increase in wavelength of electromagnetic radiation, especially of an x-ray or a gamma-ray photon, scattered by an electron.
What factor effects the intensity of light the color of light and the type of electromagnetic radiation that is given off by the electron?
Photoelectric effect
What will happen if the earth started rotating faster?
It would effect the earth's electromagnetic field as it is the spinning of the earth's core that creates the field.
How are electromagnetic waves formed?
they are formed when a electric field and a magnetic field couple. When ever a charged particle undergoes an acceleration it emits electromagnetic radiation. Therefore when an electron 'jumps' from a high energy quantum state to a lower energy quantum state it produces em radiation of a particular frequency. And, more precisely, EM waves are created by accelerating a charge. An electron at rest (or cruising at constant speed) has a stable electric field radiating outwards (really inwards for negative charge). If the electron is accelerated, a ripple in the field radiates outward with the speed of light, with the strongest effect perpendicular to the electron's vector of acceleration and weakest part (zero) along the vector. The electric field fluctuation is in any plane along the vector, and the magnetic part is in the plane perpendicular to that and the vector.
What is the effect of adding more coils of wire to an electromagnetic?
Increasing the coils will increase the strength of the magnetic field.

One important effect derived from electricity?
electromagnetic field around a conductor when ever current flows through it.
What will happen if the earth starts rotating at a faster speed?
I'm sure it would effect the earth's electromagnetic field as it is the spinning of the earth's core that creates the field.
What is the Production of light in an atom?
When atoms are heated they vibrate, and vibrating electrons will give off light particles, also known as photons. This is a side effect of the electromagnetic force. Every electron has an electric charge and therefore generates an electromagnetic force field which extends very far out in space (technically, it extends itself at the speed of light for as long as that electron has existed). So when an electron vibrates, its associated force field also vibrates, and the resulting forces that are transmitted along that force field are equivalent to a particle of light. Waves and particles are not separate phenomena at the sub-atomic level, they are just two ways of looking at the same thing (sometimes called wavicles).
What are three things you need to make an electromagnetic?
Three things you need to make an electromagnetic are a magnetic field, an electric current, and a conductor or coil of wire. When an electric current flows through the conductor, a magnetic field is created around it, resulting in an electromagnetic effect.
