How to convert length units to inverse cm

Click For Summary
SUMMARY

The discussion centers on the conversion of length units, specifically angstroms and nanometers, to inverse centimeters (cm^-1). Participants clarify that length units and spatial frequency units represent fundamentally different concepts, making direct conversion impossible. The context of using these conversions arises from applications involving the Fabry-Perot interferometer, although the necessity and practicality of such conversions are questioned.

PREREQUISITES
  • Understanding of length units such as angstroms and nanometers
  • Knowledge of spatial frequency concepts, particularly inverse centimeters (cm^-1)
  • Familiarity with the Fabry-Perot interferometer and its applications
  • Basic principles of unit conversion and dimensional analysis
NEXT STEPS
  • Research the principles of the Fabry-Perot interferometer and its operational mechanics
  • Explore the relationship between length units and spatial frequency units in physics
  • Learn about dimensional analysis and its applications in unit conversion
  • Investigate alternative units of measurement relevant to optical physics
USEFUL FOR

Physicists, optical engineers, and students studying wave optics or interferometry who need to understand the implications of unit conversions in experimental setups.

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.
