A spoon partially inserted in beaker filled with water seems bent. Explain.

Explanation

To explain why a spoon partially inserted in a beaker filled with water seems bent, we can break down the explanation into several clear steps:

When light travels from one medium to another (in this case, from water to air), it changes speed, which causes it to change direction. This phenomenon is known as refraction.

### Step 2: The Setup
Imagine a beaker filled with water and a spoon partially submerged in it. The part of the spoon that is in the water appears to be at a different position than the part that is above the water.
