Answer:
When a pencil is placed in water, it appears to be bent at the surface of water due to 1. refraction of light
Explanation:
The pencil appears bent because of "refraction". 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.
