Are you suggesting that the movement of the grating somehow changes the
(absolute) wavelength of the light?

No such thing as (absolute) wavelength of light. That would be the
point.

The whole basis of modern metrology is the ABSOLUTE wavelengths of light.


I don't know *where* you would have gotten such a stupid idea.
Modern metrology is based on wavelengths from a source with zero
relative motion. Read the instruction manual that comes with your
metrology standards kit.
