Explanation
## Step 1This problem is related to the concept of refraction in optics, a branch of physics. Refraction is the bending of light as it passes from one medium to another. ## Step 2When a pencil is placed in a cup of water, we observe it as bent or broken. This is due to the light coming from the pencil bending (or refracting) as it transitions from the water (the medium with a different refractive index) to the air (the medium with a different refractive index). ## Step 3This bending of light changes the apparent position of the pencil, making it look as though it's broken or bent. This is because we're not seeing the actual position of the pencil, but rather an apparent broken figure skewed by the refracted light.
