Tips & Best Practices
-
Ensure the input wavelength is specified in nanometres (nm) for accurate conversion.
-
Use the converted results for comparative or theoretical analyses across scales.
-
Remember the conversion assumes consistent wave speed and linear unit scaling.
-
Apply this converter primarily to relate optical or electromagnetic wavelengths to large-scale waves.
Limitations
-
Does not consider variations in wave propagation speed due to different media.
-
Nanometre-scale wavelengths typically represent electromagnetic waves, while kilometre-scale applies to longwave radio or geophysical waves.
-
Conversion is mainly meaningful for theoretical comparison, not direct physical equivalence.
