what is the term used for "study of lightning"?

I think that would fall under "meteorology".  I have never heard of a separate term for it.

Hi, chris........both are actually the result of same thing,....\n\nwhen two clouds come together, there is electric discharge,\n\na cloud can be seen as a large capacitor.......\n\nso sound and light are produced at the same time.......\n\nsince sound travels at 330 mph, and light at 300000 mps\n\nsound reaches us later coz its very slow compared to light, so we see light immediately but it takes time for the sound to reach our ears..........\n\nwhich is better??? one doesnt happen without the other....\n\nthe power generated in a lightning is 50000 volts......\n\nscientists are trying to store the power these days, \n\nthe same they cant do with sound, and lighting is obviously more dangerous......

Lightning can be any color. It is reflected off things that are near it, so it could be any color.

At a guess I would say it was St. Elmos Fire.... No, not the movie... St. Elmos Fire is Ball Lightning. While not a whole lot is known about ball lightning it is very cool. I wish I had more information for you.

All phenomena are based on energy transfer in some form.\n\nPhysics is the study of energy transfer.\n\nJules is correct about math being the fundamental structure of physics.

http://en.wikipedia.org/wiki/Biefeld-Brown_effect\n\nThe Biefeld-Brown effect is an electrokinetic effect that was discovered by Thomas Townsend Brown (USA) and Dr. Paul Alfred Biefeld[?] (CH). The effect is more widely referred to as electro-hydrodynamics (EHD) or sometimes electro-fluid-dynamics, a counterpart to the well-known magneto-hydrodynamics[?]. \n\nThe effect relies on corona discharge[?], which allows atoms to become ionized very easily near sharp points and edges – this is why lightning rods are pointy. In this case two electrodes are used with a high voltage between then, about 20kV, where one electrode is small or sharp, and the other larger and smoother. This creates a high field gradient around the smaller, positively charged electrode. Around this electrode, electrons are stripped off the atoms in the surrounding medium, they are literally pulled right off by the electrode's charge. The electrons quickly move to the electrode, and are driven to the negative electrode by the voltage. \n\nThis leaves a cloud of positively charged ions in the medium, which are attracted to the negative electrode. This also drags along some of the surrounding medium, causing what is known as ion wind, which creates a breeze of considerably greater magnitude than the ions themselves account for. This effect can be used for propulsion and fluid pumps. \n\n\nNow I get to ask a question:\n\nDo people not know how to use a search engine on their own or do they just spend hours thinking up questions to pose that they really don't want the answers to?

The first process in the generation of lightning is the forcible separation of positive and negative charge carriers within a cloud or air. The mechanism by which this happens is still the subject of research, but one widely accepted theory is the polarisation mechanism. This mechanism has two components: the first is that falling droplets of ice and rain become electrically polarised as they fall through the atmosphere's natural electric field, and the second is that colliding ice particles become charged by electrostatic induction. Once charged, by whatever mechanism, work is performed as the opposite charges are driven apart and energy is stored in the electric fields between them. The positively charged crystals tend to rise to the top, causing the cloud top to build up a positive charge, and the negatively charged crystals and hailstones drop to the middle and bottom layers of the cloud, building up a negative charge. Cloud-to-cloud lightning can appear at this point. Cloud-to-ground lightning is less common. Cumulonimbus clouds that do not produce enough ice crystals usually fail to produce enough charge separation to cause lightning.\n\nWhen sufficient negatives and positives gather in this way, and when the electric field becomes sufficiently strong, an electrical discharge occurs within the clouds or between the clouds and the ground, producing the bolt. It has been suggested by experimental evidence that these discharges are triggered by cosmic ray strikes which ionise atoms, releasing electrons that are accelerated by the electric fields, ionising other air molecules and making the air conductive by a runaway breakdown, then starting a lightning strike. During the strike, successive portions of air become conductive as the electrons and positive ions of air molecules are pulled away from each other and forced to flow in opposite directions (stepped channels called step leaders). The conductive filament grows in length. At the same time, electrical energy stored in the electric field flows radially inward into the conductive filament.\n\nWhen a charged step leader is near the ground, opposite charges appear on the ground and enhance the electric field. The electric field is higher on trees and tall buildings. If the electric field is strong enough, a discharge can initiate from the ground. This discharge starts as positive streamer and, if it develops as a positive leader, can eventually connect to the descending discharge from the cloud.\n\nLightning can also occur within the ash clouds from volcanic eruptions[1],[2], or can be caused by violent forest fires which generate sufficient dust to create a static charge.\n\nA bolt of lightning usually begins when an invisible negatively charged stepped leader stroke is sent out from the cloud. As it does so, a positively charged streamer is usually sent out from the positively charged ground or cloud. When the two leaders meet, the electric current greatly increases. The region of high current propagates back up the positive stepped leader into the cloud. This "return stroke" is the most luminous part of the strike, and is the part that is really visible. Most lightning strikes usually last about a quarter of a second. Sometimes several strokes will travel up and down the same leader strike, causing a flickering effect. This discharge rapidly superheats the leader channel, causing the air to expand rapidly and produce a shock wave heard as thunder.\n\nIt is possible for streamers to be sent out from several different objects simultaneously, with only one connecting with the leader and forming the discharge path. Photographs have been taken on which non-connected streamers are visible such as that shown on the right.\n\nThis type of lightning is known as negative lightning because of the discharge of negative charge from the cloud, and accounts for over 95% of all lightning.\n\nAn average bolt of negative lightning carries a current of 30 kiloamperes, transfe

natural LIGHTING comes from the sun,\notherwise, usually from an electric light bulb\n\nHowever, LIGHTNING, is a dual attraction between the sky and the ground, but physically speaking the negative charge in the sky is seeking out a positive charge on the ground, the LIGHTNING comes FROM THE SKY.\nHowever, you may not often see this and since there is a return of the lightning energy back up to the sky, (to balance the energy) so if you look after the sound of thunder you are seeing the return.

There are eight diffrent kinds  of lightning \nthere is a upward stroke but the first is downward  so your both right but the down comes first......\n the website below has all the info on lightning all eight kinds. I hope it was a good bet to win..

Electrostatics is the study of static or non time varying electric fields.\n\nElectromagnetics is the more general term applied to the study of electric and magnetic force fields.  Usually most situations deal with time varying currents producing time varying magnetic fields.  Maxwell's equations show us that time varying magnetic fields produce time varying electric fields.\n\nThe rest of electromagnetics is the study of the physical properties of these force fields, how they behave in a conductor, how antennas can radiate these fields, etc.

i beleve it all has something to do with the flow of electrons. Magnitism can create electricity and electricity can create magnitism.

It wasn't really invented by Benjamin Franklyn but it was discovered by him. He was the first to realise that lightning was a power that somehow could be harnessed for the good of mankind. It was other scientists in Europe who actually did harness the power. But before all that, there were parlor toys people used to catch static electricity and show sparks but that type is not powerful.Edison had nothing to do with the creation of electricity but his genius invented a ton of stuff for us to use it in.
