When a pencil is submerged in water, the refraction of light causes it to bend. This is due to refraction, which produces a visible change in the location of the pencil’s portion within the water. If water is substituted with a considerably denser liquid, the bending of the pencil will increase. This indicates that the denser the material is optically, the greater the refraction of light beams.
