How Is the Red Part of Stratton's Equation Derived from Light Pressure?

Click For Summary

Discussion Overview

The discussion centers around the derivation of a specific part of Stratton's equation, referred to as the "RED" part, which is said to result from light pressure. Participants are seeking clarification on how this portion of the equation can be derived, as the original source does not provide a derivation.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses confusion about the derivation of the "RED" part of Stratton's equation, noting that the original source does not provide this derivation.
  • Multiple participants inquire about "reference 19," indicating a possible source or citation that may clarify the derivation.
  • Another participant mentions they do not have access to the relevant book and cannot assist at the moment, suggesting a need for further input from others.

Areas of Agreement / Disagreement

Participants generally agree that the derivation of the "RED" part is unclear and that further clarification is needed. However, there is no consensus on how to derive it, and the discussion remains unresolved.

Contextual Notes

There are limitations regarding access to the original source material, which may affect the ability to derive the "RED" part. The discussion also reflects uncertainty about the content of "reference 19."

Hi everyone, initially I would like to put into words that this equation in my attachment is provided by Julius Adams Stratton but he do not derive the equation. The only part I do not understand and can not derive is the "RED" part. He just says it results from light pressure. So, I would like to ask : How can we reach this formula painted with RED? How do we derive this part ?

Additionally, I have the book but nothing is derived...So, Any idea related to how to derive the "RED" part?
 
@DrClaude Could you express something about my question after I shared the reference?

I dinät have access to that book right now, so I can't help for the moment. Maybe someone else will chime in in the mean time.
