Behavior of Waves

1. Reflection

1.1. BD: Occurs when a wave bounces off a surface that it cannot pass through

1.2. MD: When waves are incapable of passing through a surface

1.3. Example: Pool

2. Refraction

2.1. BD: Bending of a wave as it enters a new medium at an angle

2.2. MD: Occurs when a wave bends going through a new medium at an angle

2.3. Example: Lawnmower

3. Destructive Interference

3.1. BD: When two or more waves combine to produce a wave with a smaller displacement

3.2. MD: When tow or more waves combine to make a wave with a smaller displacement

3.3. Example: Speakers

4. Diffraction

4.1. BD: Bending of a wave as it move as it moves around an obstacle or passes through a narrow opening

4.2. MD: When a wave bends due to passing through a narrow space or moving around an obstacle

4.3. Example: Throwing a pebble in water

5. Interference

5.1. BD: Occurs when two or more waves overlap and combine together

5.2. MD: When two waves overlap and combine

5.3. Example: Sandbar

6. Constructive Interference

6.1. BD: Occurs when two or more waves combine to produce a wave with a larger displacement.

6.2. MD: When two or more waves combine to make a wave with a larger displacement

6.3. Example: Pushing a kid on a swing

7. Standing Waves

7.1. BD: A wave that appears to stay in one place

7.2. MD: A wave that doesn't move

7.3. Example: Guitar String
