Verify particle nature of electron using blackbody radiation

Click For Summary

Discussion Overview

The discussion centers around the relationship between blackbody radiation and the particle nature of electrons, particularly in the context of a 12th-grade physics curriculum. Participants seek clarification on how blackbody radiation can be used to verify the particle nature of electrons, while also questioning the source of the information presented.

Discussion Character

  • Exploratory
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant asks for clarification on how blackbody radiation can verify the particle nature of electrons, referencing a textbook.
  • Several participants emphasize the importance of citing the source of the information, requesting details about the book, including author, title, publication date, and page number.
  • A participant notes that the mention of blackbody radiation in the context of verifying the particle nature of electrons was presented as a question in the textbook, suggesting that context is crucial for understanding the claim.
  • Another participant mentions that the particle model for the electron is assumed in deriving the radiation law but states that the particle model is not confirmed by blackbody experiments.
  • Historical context is provided, indicating that the particle nature of the electron was suggested by J.J. Thomson's experiments in 1897 and later verified by Millikan in 1909, with a mention of Planck's work on blackbody radiation occurring in this timeline.

Areas of Agreement / Disagreement

Participants generally agree on the need for proper citation of sources but do not reach a consensus on the relationship between blackbody radiation and the particle nature of electrons. The discussion remains unresolved regarding how blackbody radiation can verify this particle nature.

Contextual Notes

Participants express uncertainty about the coverage of blackbody radiation in 12th-grade curricula and the implications of the historical context on the understanding of the particle nature of electrons.

It's mentioned in my book that blackbody radiation can verify the particle nature of electron could anyone explain this to me,please?

Which book and what exactly does it say? It's impossible for us to say anything sensible when you don't tell us what the starting point is.

It's just mentioned as a question after the lesson in which blackbody is explained briefly the book is for 12th grade

That doesn't really answer Nugatory's question.

I don't know if you are in Grade 12, or if you were looking at a book for Grade 12, but when someone asks you for the "source", in this case, a book, you need to cite the following information from the book:

1. Name of author
2. Title of book
3. Date of publication
4. The relevant page number.

This may appear to be a pain, but in this forum, we CARE about the SOURCE, and thus, a careful citation of the source is important. This also has a positive intended effect to members who stick around. They get into the habit of examining not only the source, but also the nature of the source (which, in my opinion, is a habit that is sadly lacking in most people).

Zz.

... only it was not mentioned in your book was it, according to a later post, what actually happened was:
It's just mentioned as a question after the lesson in which blackbody is explained briefly the book is for 12th grade...
OK - so it was actually mentioned as part of a question, after the lesson.
Who mentioned it? The teacher? A student? Was it part of a question like: "Does blackbody radiation verify the particle nature of the electron?" Context is everything.

US 12th grade is NZy12-13 ... senior secondary school.
Blackbody radiation is not usually covered in a lot of detail at that level ... so it is difficult to respond without knowing your source.

Breifly, for those googling here later, the particle model for the electron (at least, for matter) is assumed when texts derive the radiation law (by treating the cavity walls as mass-on-a-spring systems).
afaik The particle model is not confirmed by blackbody experiments.
Histrically, the "electron is a particle" idea was indicated from experiments done by J J Thompson in 1897 and verified by Millikan in 1909. Plank was working on blackbody radiation between these two and his model of the atom had negatively charged rings (saturnian model).
