Kerr effect
E1264869
UNEXPLORED
The Kerr effect is an optical phenomenon in which the refractive index of a material changes in response to an applied electric field, leading to field-induced birefringence.

How this entity was disambiguated
This entity first appeared as the object of triple T17353938 — 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.

Target entity: Kerr effect Context triple: [John Kerr, knownFor, Kerr effect]
-
A.
Kapitza–Dirac effect
The Kapitza–Dirac effect is a quantum phenomenon in which a beam of particles, such as electrons or atoms, is diffracted by a standing wave of light, demonstrating the wave-particle duality of matter.
-
B.
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.
-
C.
Cotton–Mouton effect
The Cotton–Mouton effect is a magneto-optical phenomenon in which a transverse magnetic field induces birefringence in an otherwise isotropic medium, causing the polarization of transmitted light to change.
-
D.
Purcell effect
The Purcell effect is a quantum electrodynamics phenomenon in which the spontaneous emission rate of an emitter is enhanced or suppressed by its surrounding electromagnetic environment, such as a resonant cavity.
-
E.
Talbot effect
The Talbot effect is a near-field optical phenomenon in which a periodic structure illuminated by coherent light produces self-images at regular intervals along the propagation direction.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
