Waves

1. Reflection

1.1. When a wave bounces off a surface it cant pass through.

1.2. When you see an object inside another

1.3. Water or a mirror

2. Constructive Interference

2.1. Two or more waves combine to produce a wave with a larger displacement.

2.2. Two waves that combine to make a big wave with alot of force.

2.3. Pushing a swing

3. Interference

3.1. When to or more waves overlap and combine together

3.2. Two waves colliding together

3.3. two balls or two rocks

4. Destructive Interference

4.1. Two waves combine to produce a wave with smaller displacements

4.2. Two waves combine at a bad time and cause bad force.

4.3. pushing the swing at the wrong time

5. Diffraction

5.1. The bending of a wave as it moves around and obstacle or passes through a narrow opening.

5.2. The way an object spreads after passing through a narrow opening.

5.3. Water through a funnel

5.4. Sand through a funnel

6. Refraction

6.1. The bending of a wave as it enters a new medium at an angle.

6.2. When the reflection seems to split

6.3. Straw in a glass of water or a guy swimming in a pool

7. standing waves

7.1. A wave that appears to stay in one place

7.2. A wave that seems like its not moving

7.3. Guitar string or violin string
