  1. Sound & Waves Review A Brief Glance at the Main Topics of Sound Physics 432

  2. Types of Waves Example: Sound

  3. Labeling Parts of a Wave

  4. Equation

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

  6. Two Source Interference • Two sources of sound each creating sound waves. • Sound waves experience constructive and destructive interference creating loud spots and soft spots. • Calculation only deals with the placement of the loud spots. • Equation: Website Used In Class: http://id.mind.net/~zona/mstm/physics/waves/interference/twoSource/TwoSourceInterference1.html

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

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

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

  10. Doppler Effect

  11. Sonic Boom and Mach Speed

  12. Beats

  13. More Beats
