Which material has an index of refraction of 1.59?

• A. Trivex
• B. CR-39
• C. Polycarbonate
• D. Glass

Answer: (C)

The material with an index of refraction of 1.59 is indeed glass. The index of refraction is a measure of how much light slows down and bends when entering a medium. In optics, different materials have characteristic refractive indices, which affect how lenses made from these materials will perform. Glass, traditionally used in eyewear and lenses, typically has a higher refractive index compared to plastics like CR-39 and polycarbonate. Trivex, on the other hand, is designed to be lightweight and impact-resistant, with a lower index of refraction commonly around 1.53. CR-39, a popular plastic lens material, has a refractive index of about 1.50. Polycarbonate, known for its high impact resistance, has a refractive index closer to 1.58. Therefore, while polycarbonate has a similar refractive index, glass is specifically recognized for having the index of 1.59, making it the correct answer for this question.
