Behavior Of Waves

1. Reflection

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

1.2. My Def: When a wave is not able to pass through a surface so it bounces it.

1.3. Example: Mirror

2. Refraction

2.1. Book Def: The bending of waves it enters a new medium at an angle.

2.2. My Def: When waves bend at an angle due to anew medium.

2.3. Example: Ocean Waves

3. Diffraction

3.1. Book Def: The bending of a wave as it moves around an obstacle or passes through a narrow opening.

3.2. My Def: When waves refract to move around an obstacle or ass through a narrow opening.

3.3. Example: Water moving around a rock.

4. Interference

4.1. Book Def: Occurs when two or more waves overlap and combine together.

4.2. My Def: When two or more waves meet and form one wave.

4.3. Example: Two water waves from different streams flow out into a river.

5. Constructive Interference

5.1. Book Def: Occurs when two or more waves combine to produce a wave with larger displacement.

5.2. My Def: When two or more waves meet and come together to make a wave with larger displacement.

5.3. Example: A mom pushing her kid on the swing with right timing making the kid swing higher.

6. Destructive Interference

6.1. Book Def: Occurs when two or more waves combine to produce a wave with smaller displacement.

6.2. My Def: When two or more waves meet and come together to make a wave with smaller displacement.

6.3. Example: Mother has bad timing on pushing her kid on the swing, so the kid will not wing as high.

7. Standing Wave

7.1. Book Def: A wave that appears to stay in one place-it does not seem to move through the medium.

7.2. My Def: A wave that doesn't look to be traveling through the medium.

7.3. Example: Two people shaking either end of a jump rope.

8. Resonance

8.1. Book Def: The response of a standing wave to another wave of the same frequency.

8.2. My Def: The reply of a standing wave to another with the same frequency.

8.3. Example: Piano
