Question

When a ray of light travelling in glass enters into water obliquely:

(a) it is refracted towards the normal
(b) it is not refracted at all
(c) it goes along the normal
(d) it is refracted away from the normal

Answer 1

 it is refracted away from the normal
Because if a ray of light goes form a denser medium (glass) to a rarer medium (water), it bends away from the normal.
