Identify the INCORRECT pair regarding the material media and their refractive index?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Benzene – 2.42.
The incorrect pair is "Benzene – 2.42."
Benzene has a refractive index of approximately 1.50, not 2.42. The other pairs are correct: Sapphire has a refractive index of 1.77, Kerosene is around 1.44, and Ruby has a refractive index of 1.71. The refractive index represents how light propagates through a medium, with higher values indicating greater light bending. Benzene, being a simple liquid hydrocarbon, has a refractive index closer to 1.5, unlike the 2.42 value mentioned.
