Answer 2

Answer:

One when it enters the glass slab from air and second time when it enters the air through glass slab. When light rays travelling through air enters glass slab, they get refracted and bend towards the normal. ... Since the ray of light I know travelling from denser medium to rarer medium, it bends away from the normal.
