How this entity was disambiguated
This entity first appeared as the object of triple T7570593 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: Abbe diffraction limit Context triple: [Rayleigh criterion, comparedWith, Abbe diffraction limit]
-
A.
Rayleigh criterion
The Rayleigh criterion is a fundamental limit in optics that defines the minimum angular separation at which two point sources can be distinguished as separate due to diffraction.
-
B.
Airy disk
An Airy disk is the central bright spot in the diffraction pattern formed when light passes through a circular aperture, fundamentally limiting the resolving power of optical systems.
-
C.
Fraunhofer diffraction
Fraunhofer diffraction is the far-field diffraction pattern of waves, typically light, observed when both the source and observation screen are effectively at infinite distance or made so with lenses, producing characteristic interference patterns.
-
D.
Rayleigh–Sommerfeld diffraction theory
Rayleigh–Sommerfeld diffraction theory is a more rigorous scalar diffraction formulation that corrects limitations in Kirchhoff’s approach by using boundary conditions consistent with the wave equation.
-
E.
Kirchhoff diffraction theory
Kirchhoff diffraction theory is a classical wave optics framework that models light propagation and diffraction by treating wavefronts as superpositions of secondary spherical waves emitted from an aperture.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
