Answer :
Grouping the labels according to which behavior of light they describe:
1. Reflection:
- Light bounces off of objects.
2. Refraction:
- Light bends as it passes through something.
- Light changes speed.
- Light changes direction.
Therefore, you can group the labels as follows:
- Reflection: Light bounces off of objects.
- Refraction: Light bends as it passes through something, changes speed, and changes direction.
