To determine the index of refraction of a medium, we need to use the formula:
Index of Refraction = Speed of Light in Vacuum / Speed of Light in the Medium
The speed of light in a vacuum is a constant value, which is approximately 3 x 10^8 m/s.
Given that the speed of light in the medium is 1.987 x 10^8 m/s, we can calculate the index of refraction as follows:
Index of Refraction = (Speed of Light in Vacuum) / (Speed of Light in the Medium)
= (3 x 10^8 m/s) / (1.987 x 10^8 m/s)
= 1.51
Therefore, the index of refraction of the medium is 1.51.
