Question

(ii) A glass slab made of a material of refractive index nį is kept in a medium of refractive index n2.
A light ray is incident on the slab. Draw the path of the rays of light emerging from the glass slab,
if (a) nj> nz (b) ni = n2 (C) nj<n2

Answer 1

Answer:

Explanation:

{i} N1 ⊃N2

the ray entering the glass slab will get refracted toward the normal

{ii}N1=N2

the ray entering the glass slab passes through the glass without any refraction .

{iii}N1⊂N2

the ray entering the glass slab will get refracted away from the normal
