libhkl gets the wavelength on a reflection from hkl.calc.wavelength in its setter:

hklpy/hkl/user.py

Line 205 in 19b397a

# TODO: How does libhkl get the wavelength on a reflection?

It is read in two places:

hklpy/hkl/calc.py

Lines 170 to 173 in 19b397a

	@property
	def wavelength(self):
	"""The wavelength associated with the geometry, in angstrom"""
	return self._geometry.wavelength_get(self._units)

and

hklpy/hkl/sample.py

Line 412 in 19b397a

wavelength=geom.wavelength_get(1),
