light thus confined is called polarized
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'by certain optical devices they may be confined to a single plane, and light thus confined is called polarized,' which directly supports the subject-predicate-object relationship that polarized light is light confined to a single plane.
- qualifier_fidelity 0.90 pass — The claim is nearly faithful to the passage. All qualifiers are appropriate: viewpoint is correctly attributed to 'author' (the passage presents this as general knowledge, not from a named source), stance is 'asserts' (the passage states this definitively), sentiment is neutral (no evaluative language), time qualifiers are properly null (no temporal scope given), and context correctly reflects 'by certain optical devices.' The quote is verbatim and supports the claim. Minor note: the claim's predicate 'is light confined to' slightly reorders the passage's phrasing 'light thus confined is called polarized,' but this is a reasonable paraphrase that maintains fidelity to the core meaning.
Polarized light, as used in the polariscope, is obtained from the Nicol prism or some development of it
judge verdicts (2)
- groundedness 1.00 pass — This claim is directly stated in the passage with an exact quote. The passage explicitly asserts that 'Polarized light, as used in the polariscope, is obtained from the Nicol prism or some development of it.'
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual information without attribution to a named source). The stance is correctly marked as 'asserts' - the passage states this as fact. Sentiment is neutral, matching the passage's objective tone. Time qualifiers are correctly null as the passage provides no temporal scope. The context 'as used in the polariscope' is accurately drawn from the passage. The quote is verbatim and directly supports the claim.
the property of sucrose to rotate a ray of polarized light to the right
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'The practical working of the polariscope is based upon the property of sucrose to rotate a ray of polarized light to the right.' The passage explicitly asserts this property of sucrose without qualification or ambiguity.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (implicit narrator of the passage). The stance is correctly marked as 'asserts' - the passage presents this as a factual property. The sentiment is neutral, matching the technical, matter-of-fact tone. The time qualifiers are all null, which is appropriate since the passage provides no temporal scope for this property. The context is empty, which is correct as the passage does not restrict the claim to a particular sense or role. The quote is verbatim from the passage and directly supports the claim about sucrose's optical property.
