How this entity was disambiguated
This entity first appeared as the object of triple T1367418 — 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.

-
A.
Fresnel equations
The Fresnel equations are fundamental formulas in optics that describe how light is partially reflected and transmitted at the boundary between two media with different refractive indices, depending on polarization and angle of incidence.
-
B.
Einstein coefficients
Einstein coefficients are parameters in quantum theory that quantify the probabilities of absorption, spontaneous emission, and stimulated emission of radiation by atoms or molecules.
-
C.
Faraday effect
The Faraday effect is a magneto-optical phenomenon in which the polarization plane of light is rotated as it passes through a material under the influence of a magnetic field aligned with the direction of propagation.
-
D.
Poynting vector
The Poynting vector is a fundamental quantity in electromagnetism that represents the directional energy flux (power per unit area) carried by an electromagnetic field.
-
E.
Fourier optics
Fourier optics is a branch of optics that uses Fourier transform methods to analyze and design optical systems, particularly the propagation and diffraction of light waves.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
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.
Input
