Please tell me in simple terms waht an 'electric dipole moment' is.?

Question

I think it means when an electron moves from one orbit to another, thus emitting light. Or is that wrong?

Answer 1

In the simplest case of a hydrogen atom (one proton and one electron) the atom is electrically neutral. However there is a non uniform charge distribution. This is because the electron orbits the proton and the do not occupy the same space.

Oscillating dipoles emit light.

Answer 2

hymn, well i think i can help you. well, lets start by looking at your theory. hmm. "when an electron moves from one orbit to another". well i don't think so sorry. this would be defined as moving from one principle energy level to another. when an electron moves from the excited state( high energy level) to the ground state (lower enbergy level) it emits spectra or light. now here we are talking about an electric dipole moment. it is very important to know what a dipole moment is first. well The electric dipole moment for a pair of opposite charges of magnitude q is defined as the magnitude of the charge times the distance between them and the defined direction is toward the positive charge. It is a useful concept in atoms and molecules where the effects of charge separation are measurable, but the distances between the charges are too small to be easily measurable. It is also a useful concept in dielectrics and other applications in solid and liquid materials. well in simple terms it is when opposite charges form or break bonds hence emmiting some sort of light or mechanical, energy.

Answer 3

In simple terms, an electric dipole is a positive charge attached to a negative charge.

While the charges cancel out, the electrical force from the two charges ONLY cancels out if they are both the same distance from the observer. If one charge is closer, it's force is stronger.

Normally, the force from an electric charge drops off as 1/r^2. But, the dipole force drops off as 1/r^4, a much sharper drop-off. That's why in most cases, equal and opposite charges appear to completely cancel each other out.

Answer 4

I am sorry2 say but your thinking is wrong answer is
an electric dipole is a system of equal and opposite charges separated by some distance and electric dipole moment isP=q X 2a q is either of 2 charges and a is distanceb /w them Pis vector quantity. more the distance more will be the dipole moment because q is constant

Answer 5

That is wrong dude.
When two oppositely charged particles are kept in a distance then the moment of force acting between the two particles is Electric dipole moment.

Answer 6

Its the moment created by the force of attraction between a positive and a negative electric charge. Its a vector quantitity with the direction vector towards the positive charge. So if in a system there is more positive charge than negative, the moment vector will tend towrds the positive charge.

Answer 7

a million)Dipole 2d refers back to the extensive-unfold of a gadget to act like a dipole. Dipole 2d is the measured polarity of a polar covalent bond. it somewhat is defined as a results of fact the product value of value on the atoms and the gap between the two bonded atoms. Its basic unit is debye and SI unit is Coulomb metre. 2)resonance is the tendency of a gadget to oscillate at optimal amplitude at specific frequencies, prevalent as a results of fact the gadget's resonance frequencies (or resonant frequencies). At those frequencies, even small periodic using forces can produce great amplitude vibrations, as a results of fact the gadget shops vibrational capability.

Answer 8

Nice Calabi-Yau manifold.
