Complete Question

Index of refraction is defined as the speed of light in a vacuum divided by the speed of light in the medium. What is the index of refraction for a glass sample? Speed of light in a vacuum c = 3.0 x 108 m/s. Speed of light in the glass = 1.50 x 108 m/s.

The  index of refraction is  

Explanation:

From the question we are told that

    The  speed of light in a vacuum is  

      The speed of the in the glass is  

From the question the index of refraction for a glass is mathematically evaluated as

it would be c. predictability
