When a pencil is placed in an empty glass tumbler, it appears as it is - a pencil. However, if you are referring to the phenomenon where the pencil appears to be bent or broken when water is added to the tumbler, this is due to refraction.

Here's a step-by-step explanation:

1. When light travels from one medium to another (in this case, from air to glass to water), it changes speed, which causes it to bend or refract.

2. When you look at the pencil in the water, you're seeing it through two different mediums - the air and the water. The light from the pencil refracts, or bends, as it moves from the water to the air.

3. This bending of light makes the pencil appear to be at a different location than it actually is, causing it to look bent or broken.

4. If you were to remove the water, the pencil would appear as it actually is because the light would only be traveling through one medium (air) and wouldn't be refracting.
