Looking at a straight object, such as a pencil in the figure here, which is placed at a slant, partially in the water, the object appears to bend at the water's surface. In fact, if it’s hand blown glass, then symmetry is essential to the creation process! ii) Refraction of light is the phenomenon responsible for this change.

Because the glass is so thin and because the light starts and finished in air, the refraction into and out of the glass causes little deviation in the light's original direction.) Light waves travel faster thought air (which is a less dense material) than they do through water or glass (a more dense material). A pencil in a clear cup of water will also appear to bend. Everything we see is nothing more than lightwaves, right? Place one celery stalk in each glass, leaf–end at the top. We can see the stems above the waterline and the below the waterline.
