  1. 1. Investigating sound<br />
  2. 2. Sound<br />Form of energy that travels through matter as waves<br />Wave<br />Disturbance that transfers energy from point to point<br />
  3. 3. Frequency<br />The number of waves produced in a unit of time<br />Pitch<br />The highness or lowness of a sound<br />Amplitude<br />Measure of the amount of energy in a sound wave<br />
  4. 4. Vibration<br />The back & forth movement of matter where energy is transferred<br />
  5. 5. VACUUM (SPACE)<br />NO MATTER<br />SOUND CANNOT TRAVEL<br />
  6. 6. Transmit<br />Sound<br />Fastest<br />MOLECULES <br />OF MATTER<br />CLOSER <br />TOGETHER<br />SOLID<br />Transmit<br />Sound<br />Slowest<br />MOLECULES<br />OF MATTER<br />FARTHER<br />APART<br />GASES<br />
  7. 7. MOST OF <br />SOUND<br />ABSORBED<br />SOFT<br />OBJECT<br />SOUND WAVES<br />
  8. 8. FREQUENCY<br />PITCH<br />FREQUENCY<br />PITCH<br />
  9. 9. LOUDER<br />SOUND<br />AMPLITUDE<br />SOFTER<br />SOUND<br />AMPLITUDE<br />
