MCQ

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

A
Principal maxima of other
B
First minimum of the other
C
Half$-$way between principal maximum and first minimum.
✓
Second maximum of the other

✓

Answer

Correct option: D.

Second maximum of the other

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.
