2. Types of Waves

3. Labeling Parts of a Wave

4. Equation

5. Interference Constructive: Constructive: Adding Crests Adding Crests Adding Troughs Adding Troughs Pulses on the same Side Pulses on the same Side Creates antinodes in a standing wave Creates antinodes in a standing wave Destructive Destructive Subtracting a trough from a crest Pulses on the opposite side Creates Nodes in a standing wave

6. Two Source Interference Two sources of sound each creating sound waves. Two sources of sound each creating sound waves. Sound waves experience constructive and destructive interference creating loud spots and soft spots. Sound waves experience constructive and destructive interference creating loud spots and soft spots. Calculation only deals with the placement of the loud spots.

7. Resonance: Strings Increased amplitude because something is vibrating at a natural frequency. Increased amplitude because something is vibrating at a natural frequency.

8. Resonance: Open Tubes Know the harmonics Know the harmonics Know the overtones Know the overtones Divide the waves into quarters Divide the waves into quarters Figure out how much of the wave fits into the tube Figure out how much of the wave fits into the tube L=length of the tube L=length of the tube

9. Resonance: Closed Tubes Know the harmonics Know the harmonics Know the overtones Know the overtones Divide the waves into quarters Divide the waves into quarters Figure out how much of the wave fits into the tube Figure out how much of the wave fits into the tube L=length of the tube L=length of the tube
