Question
Two nearby objects are just resolved, if the principle maximum in the diffraction pattern of one coincides with:
✓

Answer

  1. First minimum of the other
Explanation:
The Rayleigh criterion is the generally accepted criterion for the minimum resolvable detail - the imaging process is said to be diffraction-limited when the first diffraction minimum of the image of one source point coincides with the maximum of another.
