The speed of light in a certain medium is 2.2 x 10⁸ m/s. What is the index of refraction of this medium? A)1.0 B)1.2 C)1.4 D)1.6 E)1.8

Question

Quizplus · Accepted Answer

The index of refraction (n) is calculated using the formula n = c/v, where c is the speed of light in a vacuum (approximately 3.0 x 10^8 m/s) and v is the speed of light in the medium. Substituting the given values, n = (3.0 x 10^8 m/s) / (2.2 x 10^8 m/s) = 1.36, which is closest to 1.4.
