Determine the speed of light in quartz having a refractive index of 1.54.
July 29, 2021 | education|
s = 3 * 10 ^ 8 m / s.
n = 1.54
The absolute refractive index n of a given medium is determined by the ratio of the speed of light in vacuum c to the speed of light in a given medium V.
n = s / V.
From the formula we express the speed of light in quartz: V = s / n.
V = 3 * 10 ^ 8 m / s / 1.54 = 1.94 * 10 ^ 8 m / s.
Answer: the speed of light in quartz is V = 1.94 * 10 ^ 8 m / s.
