Answer:
(i) When ray of light enters with
oblique incidence from air into water, then it goes from optical rarer medium
to optical denser medium and velocity of light decreases which in turn bends
the incident light towards the normal. Also, i > r
(ii) When ray of light enters with
oblique incidence from water into air, then it goes from optical denser medium
to optical rarer medium and velocity of light increases which in turn bends the
incident light away from the normal. Also, i< r.
