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 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
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 What unit of measure would you use to measure the volume of a chicken egg? • Milliliters • Liters • Grams • Cubic meters
A wave that moves the medium in the same direction (parallel) that the wave travels in is • Transverse • Longitudinal • Standing • Mechanical Transverse waves contain • Crest and trough • Top and bottom • Compression and rarefaction • Energy
Longitudinal waves contain • Crest and trough • A slinky • Compression and rarefaction • Particles The distance between one crest and the next crest is the wave’s • Amplitude • Wavelength • Frequency • Speed
The formula to measure speed of a wave is • A X B • Wavelength X Frequency • Frequency X Sound • A3 What are the two types of mechanical waves? • Rocky and bullwinkle • Ocean and sound • Transverse and longitudinal • Light and dark
