Question

in the following the refractive indices of two medium are shown when light travels turpentine oil to water the speed of light of _​

Answer 1

Answer:

It is known that refractive index of a medium,

, where c is speed of light in vacuum and v is speed of light in the medium. <br>

<br> i.e., light travels fastest in a medium whose refractive index is smallest, i.e., in water,
