To find the index of refraction of the medium, we can use the formula:
index of refraction = speed of light in vacuum / speed of light in the medium
The speed of light in vacuum is a known value, which is approximately 3 x 10^8 m/s.
Substituting the given value for the speed of light in the medium (2.2 x 10^8 m/s) into the formula, we have:
index of refraction = (3 x 10^8 m/s) / (2.2 x 10^8 m/s)
Calculating the result, we get:
index of refraction ≈ 1.36
Therefore, the answer is 1.36, option B.
