Question

The index of refraction of ice is

1.31. At what speed does light
travel through ice?
(Answer is * 10^8 m/s. Just fill in
the number in the blank, not the power.)

Answer 1

Answer: 2.29

Step-by-step explanation:

Answer 2

V air = 3 * 10^8 m/s

n ice = 1.31

V = Vair / n = 3 * 10^8 / 1.31 = 2.29 * 10^8 m/s
