Vedclass · Answer

(C) The refractive index of a medium is a measure of how much the speed of light is reduced when entering that medium. Air has a refractive index of approximately $1.0003$,which is the lowest among the given options. Water has a refractive index of approximately $1.33$. Glass has a refractive index ranging from $1.5$ to $1.9$ depending on the type. Diamond has a very high refractive index of approximately $2.42$. Therefore,air has the minimum refractive index.

Which of the following has the minimum refractive index?
