Who measures light wavelengths in angstroms rather than nm?

I was curious too so I checked Wikipedia [1].

Apparently, angstrom was invented exactly for measuring light wavelength.

Its (arguably more common today?) usage for atoms and other microscopic structures actually came after that.

Everyone? It’s the preferred unit for electromagnetic wavelengths.
