Yes when part of it is seen out of the water it tricks the eye
Water bends or refracts light, not only do things look bigger they are not where they appear to be.
In water objects look closer then they really are.
Refraction makes a ruler in a cup of water look broken because of the light rays bend when they move from water to air or air to water...
Most any liquid will distort light rays and make objects seen through the liquid as distorted. When you see the part of the rock through the liquid and part of it through the air, it will indeed look bent.
due to refraction If the pencil is vertical, then it shouldn't look broken.
Due to the phenomenon of refraction being caused; straw appears to be bent in water.
because of refraction of light same principle as when you look at a straw in water and it looks broken
Line segments can be broken down into points.
Objects that float in water are less dense than water; while objects that sink in water are more dense than water.
Light refraction caused by the water
Not all objects absorb water
cause they are broken in half..
