The required value of the index of refraction of glass is 1.5.
Given data:
The speed of light in a vacuum is, .
The speed of light in a glass is, .
Light has the tendency to travel from one medium to another, then the difference between the speeds of light in various mediums is determined by a term, known as the index of refraction. The mathematical expression for the index of refraction of glass is,
n = c / v
Solving as
Thus, we can conclude that the required value of the index of refraction of glass is 1.5.
