If the refractive index of a certain material with respect to air is 1

1.	If the refractive index of a certain material with respect to air is 1.5, what is the refractive index of air with respect to that material?
Answer» As the refractive index of the given material with respect to air is 1.5, the refractive index of air with respect to the material is \(\frac{1}{1.5}=\frac{1}{3/2}=\frac{2}{3}\) = 0.6667 (approximately)
