when object is in denser medium its real depth is "x" and apparent depth is "d", then refractive index is ratio of real to apparent depth ... but if object is in rarer medium and we are observing it through denser medium then how we can define refractive index ...i mean observing a object through glass slab. sir please answer to those questions which i have asked regards.
