A) Curved downwards
B) Bent towards the water surface
C) Bent in a zigzag mannar
D) Bent towards the bottom
Correct Answer: B
Solution :[b] This is due to refraction: In this case the pencil appears bent because it is entering from a rarer medium to a denser medium i.e. from air to water. When a ray enters into denser medium, it bends towards the imaginary normal line (perpendicular to the surface of contact) therefore it should be bent towards the bottom.
