The speed of light in a material is 1.74 × 10⁸ m/s. What is the index of refraction of this material? A) 1.72 B) 0.58 C) 1.74 D) 0.218

Question

Quizplus · Accepted Answer

The index of refraction (n) of a material is given by the equation n = c/v, where c is the speed of light in a vacuum (approximately 3.00 × 10^8 m/s) and v is the speed of light in the material. Using the given speed of light in the material (1.74 × 10^8 m/s), the index of refraction is n = (3.00 × 10^8 m/s) / (1.74 × 10^8 m/s) ≈ 1.72.
