The ray AO is shown in the figure given below. The path of refracted ray and emergent ray will be:
(1) the refracted ray will bend towards normal
(2) the refracted ray will bend away from normal
(3) the emergent ray will bend towards normal
(4) emergent ray will bend away from normal
- (1) and (3)

Answer
(1) and (4)
Reason — As air is a rarer medium and glass is a denser medium hence, the light ray passes from a rarer to a denser medium hence, the refracted ray will bend in towards normal whereas emergent ray will bend away from normal.
