How to convert length units to inverse cm

Click For Summary

Discussion Overview

The discussion revolves around the conversion of length units, such as angstroms and nanometers, to inverse centimeters (cm-1). The context includes potential applications in physics, specifically related to the Fabry-Perot interferometer.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant inquires about converting length units to inverse cm, providing examples like angstroms and nanometers.
  • Another participant asserts that conversion between these units is not possible, as length and spatial frequency are fundamentally different concepts.
  • A later reply indicates that the inquiry is related to the use of these units in the context of a Fabry-Perot interferometer.
  • Another participant suggests that while the conversion may not be standard, there could be unconventional interpretations, such as "barns per centimeter."

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of converting length units to inverse centimeters, with some asserting it is not possible while others entertain unconventional interpretations.

Contextual Notes

The discussion highlights the distinction between length units and spatial frequency units, which may lead to confusion in conversion attempts. There are also unresolved assumptions regarding the intended application of the conversion.

Please elaborate what you are trying to do.

In general - you can't, as one is a length unit, other is a spatial frequency unit. Different things.

i want to use it with Fabry-Perot interferometer
 
Well, you could have barns per centimer, or something like that. Not sure why you'd want it, but you cold.
