Yes, very easily. Get a glass of water and stick a straw in it. It will not look connected of straight.
Reflection and refraction

Refraction
Because of refraction of light
What is Refraction?? What is Refraction??
When a toy car travels from a plain floor to the grass lawn we see that it deflects.Similarly light too bends when it changes its medium.This bending can be seen at the boundary of the two mediums that separates them.
refraction
The change in direction is called refraction.
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.
It is Refraction
spectrum? A band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength.
