Question:
Chloroform has an index of refraction of 1.44. What is the speed of light in this medium?
A
\(2.08 \times 10^8 m/s\).
explanation
Use the following formula: n = c / v, where n is the index of refraction, c is the speed of light in a vacuum \(3.00 \times 10^8 m/s\) and v is the velocity of light in the medium.
n = c /v
1.44=\(\frac{\mathrm{300 \times 10^8 m/s} }{\mathrm{v}}\)
V=\(\frac{\mathrm{300 \times 10^8 m/s} }{\mathrm{1.44}}\)
V=\(2.08 \times 10^8 m/s\)
