Since the light that reaches to us is bended light thus the image appears thick or thin

The apparent bending of pencil in a glass of water occurs due to a phenomenon known as refraction.
The speed of light is different in different mediums such as air and water. When light travels from a rarer(less dense) to a more denser medium the object seems to bend over the intersection of two mediums.
In case of pencil and water , the pencil seems to look bended from the interference of surface if water and air.
