Where the article explains it
For a telescope with aperture diameter D observing light of wavelength , the smallest angular separation it can resolve is approximately
The passage around this formula
This reach is the approach’s defining strength and its defining limitation is spatial resolution, which is fixed by the physics of diffraction rather than by mission budget. For a telescope with aperture diameter D observing light of wavelength , the smallest angular separation it can resolve is approximately
