Why thunderbolts don't travel in straight lines

Click For Summary

Discussion Overview

The discussion revolves around the behavior of lightning, specifically why it does not travel in straight lines. Participants explore the nature of electrical charge movement, the mechanics of lightning formation, and the complexities involved in the process.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that electrical charge should move in a straight line to the Earth, as it represents the shortest path.
  • Another participant clarifies that lightning is not a "thunderbolt" but rather the movement of electrons, which travel in a more complex, non-linear path due to atomic interactions.
  • A participant notes that the speed of the lightning's descent is not the same as the speed of electron movement, highlighting the difference between the impulse speed and electron speed.
  • One contributor explains that lightning occurs when electrical charge differences become significant enough for electrons to jump between pockets of charge, creating a chain reaction effect.
  • A later reply expresses satisfaction with the previous explanation but indicates that it raises further questions about the topic.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specifics of lightning behavior, and multiple competing views and questions remain unresolved throughout the discussion.

Contextual Notes

The discussion reflects ongoing research in the field of physics regarding the mechanisms of lightning and the behavior of electrical charges in the atmosphere. There are limitations in the explanations provided, particularly regarding the atomic-level interactions and the complexities of charge differentials.

Who May Find This Useful

Individuals interested in atmospheric physics, electrical engineering, or those seeking a deeper understanding of lightning phenomena may find this discussion relevant.

Why thunderbolts don't travel in straight lines ?
I think the electrical charge likes to move in the shortest path to the Earth and the shortest path must be a straight line !

Well it's really not a "thunder" bolt since thunder is the sound produced from the expanding air. but anyway..

The lighting does take the shortest route except that you're forgetting one thing. The lighting is the passing of electrons from atom to atom. The electrons use the air as their medium of travel in this case, instead of a wire or something you that normally think of with electricity. Basically, whichever way is easiest they will take.. but you must think of it on an atomic level. It's going to be a little jumpy in the paths it takes as the impulse decends downwards.

Also a little fact, the speed it takes to get from top to bottom is not the speed the electrons move. That's the speed of the impulse. The electrons move much more slowly.

It gets much more complex than that too but I think that should be a decent explanation. :smile:
 
Last night the thunderbolt waked me up, right then this question appeared in my mind.
For such an immediate question this answer is very good and complete.
Thank you
 
This is still a heavily researched topic in physics. Sporff has it pretty much right from what I know of the subject.
 
A bolt of lightning, as you probably know, occurs when the difference electrical charge becomes great enough for a spark to jump from one club to another, or from a cloud to the ground. But that is the simplified version. In actuality, there are many pockets of charge differential throughout the air during a thunderstorm. With little pockets of higher and higher potential building up all over the place, when the imbalance between the two charges finally gets high enough, the electrons actually jump from one pocket to another, rather like "connect-the-dots ". If you can see it in slow motion, this actually has a chain reaction effect. Potential drained from one location increases the difference in potentials between that location and its neighbor, causing the neighbor to discharge, and so on.
 
What sporff told was exactly the answer I was looking for. But now with the last post some more questions are made in my mind which I just ignore them until the time that I know more of the subject :redface:
