A ray of light changes direction when it gets out of the water, and into the air. This is called "refraction".

due to refraction If the pencil is vertical, then it shouldn't look broken.
Because of refraction of light
Your eye is interpreting the path taken by the light that reflects off the pencil.
As water is a denser medium compared to air refraction occurs. Refraction causes the light to be bent before reaching our eyes. Hence, pencil looks broken.
The pencil appears bent because of "refraction". Simply put, light can't travel as fast in water as it does in the air. The difference in speed causes the image to appear to bend a bit. See the related link for more details.

Such a material is GLASS.
One example of refraction of light is a rainbow and a broken pencil when placed in a glass of water.
As water is a denser medium compared to air refraction occurs. Refraction causes the light to be bent before reaching our eyes. Hence, pencil looks broken.

Refraction. It's basically the same reason a pencil put in a glass of water appears to be "bent".
Caused by refraction. The same effect causes a depth of water to be smaller than it really is.
Any light rays crossing the air-water border will be refracted, that is, bent. So, objects above the water will appear displaced. In other words, they will appear to be where they are not. You can see this phenomenon by placing a pencil in a glass of water. The pencil appears broken and discontinuous. This optical illusion is due to refraction.
By whom has the glass been broken?
Glass is harder than the "lead", actually mostly graphite, in a pencil. Therefore, the glass can not be deformed by a pencil sufficiently to produce an adherent layer of graphite, as is required for writing.
