1.	A glass sla made of a material of refractive index n_(1) is kept in a medium of refractive index n_(2). A light ray is incident on the slab. Complete the path of rays of light emerging from theglass slab, if : (i) n_(1)gtn_(2') (ii) n_(1)=n_(2)' (iii) n_(1)ltn_(2)
Answer» Solution :(i) When `n_(1)gtn_(2)` Light goes from RARER to denser medium `:.` it diverges. (II) When `n_(1)=n_(2)` There is no CHANGE in the medium `:.` bending or refraction occurs. (III) When `n_(1)ltn_(2)` Light goes from denser to rarer medium `:.` It CONVERGES.
