Discussion Overview

The discussion revolves around the concept of "well depth" in the context of bond energy, exploring its meaning and implications in physics, particularly in quantum mechanics and potential energy landscapes.

Discussion Character

  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant seeks clarification on the term "well depth," noting difficulties due to language barriers and lack of references.
  • Another participant provides a general definition of a well, suggesting it may refer to different concepts depending on context.
  • A participant describes "energy well" as a region of lower potential energy where particles can become trapped, requiring kinetic energy to escape.
  • There is a mention of the Lennard-Jones potential in relation to the discussion, indicating a specific context within potential energy theory.
  • One participant suggests consulting quantum mechanics literature for a more comprehensive understanding of the concept.
  • A later reply explains the graphical representation of energy versus position, likening the concept to a ball trapped in a hole, where the depth of the well correlates with bond strength.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and interpretation of "well depth," with no consensus reached on a singular definition or application. Multiple viewpoints and explanations are presented without resolution.

Contextual Notes

The discussion lacks specific definitions and may depend on varying interpretations of potential energy concepts. Assumptions about the audience's familiarity with quantum mechanics and related terminology are not explicitly stated.

Who May Find This Useful

This discussion may be of interest to individuals exploring concepts in quantum mechanics, potential energy, and bond energy, particularly those seeking clarification on terminology and its implications.

hello!

what is actually the "well depth" or the "depth of the well" ?

maybe it doesn't help that english is not my native language, but anyway, I can't find some reference

I found the term to be used in context of describing the energy of the bonds

thanks!

I can't way for sure without knowing the context, but a well is a hole in the ground from which you draw or pump water. But it could mean something else in another context.
 
Sounds like your are talking about the energy well that exist in a tiny region of space surrounded by regions of higher potential energy. A place that a particle gets stuck because it needs kenetic energy to escape. Which is suppose described a hole in the ground as well.
 
in Lenard-Jones potential ?
 
Pick up a book in quantum mechanics, it will explain everything much better than we can.
 
In a graph of energy versus position, there can be a region of space where the energy is lower than other nearby regions. Graphically, this looks like a hole in the ground and if you want to picture things classically you can think about an electron being a ball trapped in the hole (an electron in a bond, say) that needs some energy put into it to get it out of the hole (break the bond). The deeper the well, the stronger the bond.
