This means,
Refractive index = Speed of light in vacuum/ speed of light in medium
2.2= speed of light in vacuum/speed of light in medium
2.2 is refractive index with reference to speed of light in vacuum.
Refractive index = Speed of light in vacuum/ speed of light in medium
2.2= speed of light in vacuum/speed of light in medium
2.2 is refractive index with reference to speed of light in vacuum.
