Q: Which of the following options represents the correct ascending order of the refractive index of certain substances? (Left to right)
  • A. Rock salt, benzene, kerosene, ice
  • B. Kerosene, ice, benzene, rock salt
  • C. Rock salt, ice, benzene, kerosene
  • D. Ice, kerosene, benzene, rock salt
Correct Answer: Option D - The refractive index (coefficient) refers to the refractive capacity of the transparent medium. The correct ascending order of the refractive index of the given substances is - ice (1.31) kerosene (1.44) benzene (1.5) rock salt (1.54).
