Answer #1

Relation between refractive index and speed of light is given as

Where n- refractive index

c- speed of light in air or vacuum=

​​​​

v- speed of light in medium

Given data for this problem is

By substituting the values of c and v in above relation of refractive index and speeds of light in vacuum and medium

This is the required value of refractive index.
