If the speed of light through an unknown liquid is measured at 2.42 × 10⁸ m/s,what is the index of refraction of this liquid? (c = 3.00 × 10⁸ m/s) A) 0.81 B) 1.24 C) 1.54 D) 1.11 E) 1.81

Question

The index of refraction (n) is calculated by dividing the speed of light in a vacuum (c) by the speed of light in the medium (v): n = c/v. Here, n = (3.00 × 10^8 m/s) / (2.42 × 10^8 m/s) = 1.24.
