how to convert length units to inverse cm.For example arngstroms,nanometers to cm^-1.Thanks

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.

Converting length units to inverse cm involves converting the unit of length to cm first, and then taking the reciprocal of that value.

To convert from angstroms to inverse cm, we can use the conversion factor 1 Å = 10^-8 cm. This means that 1 cm is equivalent to 10^8 Å. To convert to inverse cm, we simply take the reciprocal of this value, which is 10^-8 cm^-1.

Similarly, to convert from nanometers to inverse cm, we can use the conversion factor 1 nm = 10^-7 cm. This means that 1 cm is equivalent to 10^7 nm. To convert to inverse cm, we take the reciprocal of this value, which is 10^-7 cm^-1.

In general, to convert any unit of length to inverse cm, we can use the conversion factor 1 cm = 10^x, where x is the power of 10 associated with the unit. For example, 1 meter (m) is equivalent to 10^2 cm (since 1 m = 100 cm), so to convert to inverse cm, we take the reciprocal of this value, which is 10^-2 cm^-1.

It's important to note that inverse cm is a unit commonly used in spectroscopy to represent wavenumbers, which are the reciprocal of wavelength. This unit is often used to describe the energy levels of molecules and atoms, and is especially useful in the study of infrared and Raman spectroscopy.
