Answer:

1.52

Explanation:

edge 2022

The index of refraction for the piece of glass is 1.52

What is refractive index?

the ratio of the velocity of light in a vacuum to its velocity in a specified medium.

    i.e. The refractive index is given by n=c/v

where c = velocity of light in vacuum

            v = velocity of light in medium

So  here , velocity of light in vacuum= C= 2.99 x 10⁸m/s

      Velocity of light in glass = V= 1.97 x 10⁸m/s

       therefore , n= 2.99 x 10⁸/1.97 x 10⁸m/s

                         n= 1.52

  • Thus the refractive index of glass is 1.52
