Waves

1. Reflection: The interaction that happens when a wave bounces off a surface that it can't pass through.

1.1. When a wave can't pass through a surface.

1.1.1. example: A mirrior

2. Refraction: The bending of a wave as it enters a new medium at an angle

2.1. When a wave goes through a new medium at an angle.

2.1.1. Example: A wave at a beach

3. Diffraction: A wave as it moves around an object of squeezes through a narrow opening.

3.1. A wave going through a small opening.

3.1.1. Example: A jetty.

4. Interference: The interaction of two or more waves that combine in a region of overlap.

4.1. Waves that overlap

4.1.1. Example: Breaker waves

5. Constructive Interference: Creates a bigger wave.

5.1. Adding waves to make a bigger one.

6. Destructive Interference: Creates a smaller wave.

6.1. Taking away the force of a wave and making it smaller.

6.1.1. Example:Quieter sound waves.

7. Standing wave: A wave that stays in one place.

7.1. A still wave

7.1.1. Example: A constant sound wave.

8. Resonance: The response of two standing waves.

8.1. Two standing waves colliding.

8.1.1. A dramatic change in frequency
