  3. Bill Nye Bill Nye and Understanding WAVES

  4. A wave is a disturbance in a medium Parts of a Wave

  5. Types of Waves

  6. Rueben’s Tube http://www.youtube.com/watch?v=HpovwbPGEoo Sound waves visualized

  7. Torsional waves Tacomo Narrows Bridge http://www.youtube.com/watch?v=3mclp9QmCGs

  8. When 2 sounds (notes) are played at the same time and the frequencies differ by a small amount, a beat can be heard. Example 1: Note #1 = 345Hz Note #2 = 347Hz Difference = 2Hz Therefore a beat will be heard. Example 2: Listen… Beat frequencies

  9. Doppler Effect Christian Doppler proposed in 1842 Frequency heard by obs. Velocity of sound Velocity of source (going away +ve, coming toward –ve) Frequency generated by obj.

  10. Why are waves important?

  11. Applications Sound… • Travels in solids, liquids and gases • It can be measured Microwaves • Heat our food • Can be used to measure the speed of light Ultrasounds, MRIs, CT, X-rays • All can be used in medicine Doppler, RADAR, LASER • Science inventions that use the properties of waves
