A liquid has an index of refraction of 1.33.What is the speed of light through it? (c = 3.00 × 10⁸ m/s) A) 3.99 × 10⁸ m/s B) 2.26 × 10⁸ m/s C) 4.46 × 10⁸ m/s D) 2.04 × 10⁸ m/s

Question

Quizplus · Accepted Answer

The speed of light in a medium is given by v = c/n, where n is the index of refraction. Therefore, the speed of light in this particular liquid is v = (3.00 × 10^8 m/s) / 1.33 = 2.26 × 10^8 m/s. The correct choice is B.
