  1. 10/14/09 1. Picture a tub filled with water, with a toy boat floating on the water. You plunge your fist into the water, next to the toy boat. What will happen to the boat? • It will sink • It will move up and down • It will not move • It will travel straight to the other end of the tub 2.What will happen to the surface of the water? • Waves will move out from the disturbance • The water will remain calm • A wave will move from the surface to the bottom of the tub • The water level will go down

  2. 10/15/09 1. The changing pitch of a police car’s siren as it moves away from you is an example of… • The Doppler effect • Resonance • The speed of sound • Intensity 2. What unit of measure would you use to measure the volume of a chicken egg? • Milliliters • Liters • Grams • Cubic meters

  3. 10/16/09 1. A wave that moves the medium in the same direction (parallel) that the wave travels in is • Transverse • Longitudinal • Standing • Mechanical 2. Transverse waves contain • Crest and trough • Top and bottom • Compression and rarefaction • Energy

  4. 10/19/09 1. Longitudinal waves contain • Crest and trough • A slinky • Compression and rarefaction • Particles 2. The distance between one crest and the next crest is the wave’s • Amplitude • Wavelength • Frequency • Speed

  5. 10/20/09 1. The formula to measure speed of a wave is • A X B • Wavelength X Frequency • Frequency X Sound • A3 2. What are the two types of mechanical waves? • Rocky and bullwinkle • Ocean and sound • Transverse and longitudinal • Light and dark
