Answer:

Explanation:

The formula for calculating the index of refraction is expressed as

n = c/v

where

n is the index of refraction

v is the speed of light in the medium

c is the speed of light in vacuum and its value is 3 x 10^8 m/s

From the information given,

v = 2.76 x 10^8 m/s

Thus,

n = 3 x 10^8 m/s/2.76 x 10^8 m/s

n = 1.09

the index of refraction of the medium is 1.09
