To find the medium's index of refraction, we can use the equation:
Index of refraction (n) = Speed of light in a vacuum (c) / Speed of light in the medium (v)
Given the average speed of light in the medium is 2.2x10^8 m/s, we need to know the speed of light in a vacuum. The speed of light in a vacuum is a constant, which is approximately 3.0x10^8 m/s.
Now we can substitute the values into the equation:
n = (3.0x10^8 m/s) / (2.2x10^8 m/s)
To simplify, we divide the numerator and denominator by 10^8:
n = (3.0 / 2.2) x (10^8 / 10^8)
Calculating the division gives us:
n = 1.36
Therefore, the medium's index of refraction is approximately 1.36.
