Cal the index of refraction for a medium in which the speed of light is 2.012*10^8 meter per seconds

To calculate the index of refraction (n) for a medium, you need to know the speed of light in a vacuum (c) and the speed of light in the medium (v). The formula for calculating the index of refraction is:

n = c / v

Given that the speed of light in a vacuum is approximately 3.0 x 10^8 meters per second (c = 3.0 x 10^8 m/s) and the speed of light in the medium is 2.012 x 10^8 meters per second (v = 2.012 x 10^8 m/s), we can substitute these values into the formula:

n = (3.0 x 10^8 m/s) / (2.012 x 10^8 m/s)

Simplifying this equation, we get:

n ≈ 1.49

Therefore, the index of refraction for a medium in which the speed of light is 2.012 x 10^8 meters per second is approximately 1.49.
