Answer 1

Here are the terms that accurately complete each statement:

1. **Refraction** is the bending of waves due to a change in speed.
2. **Reflection** occurs when all or part of a wave is unable to pass through something and bounces back.
3. When waves move around barriers or through openings in a barrier, it is called **diffraction**.

So the complete statements would read:

- Like all waves, light waves change direction by reflection, refraction, and diffraction.
- **Refraction** is the bending of waves due to a change in speed.
- **Reflection** occurs when all or part of a wave is unable to pass through something and bounces back.
- When waves move around barriers or through openings in a barrier, it is called **diffraction**.
