  1. Review for CIA 2-2

  2. We are learning to: describe the properties of waves.We are looking for: Wavelength-distance from crest to crest (transverse wave), or from compression to compression (longitudinal wave)Frequency-number of waves that pass a given point each secondAmplitude-distance from rest position to the crest (transverse wave); measures how compressed the particles of the medium are (longitudinal wave); determines the amount of energy of each wave

  3. In the diagram, identify the wave property “A” • Frequency • Amplitude • Wavelength • Help! I don’t understand.

  4. Which of the following is true about waves in the diagram? • Wave X has a higher frequency than Wave Y • Wave X has a lower frequency than Wave Y • Wave X has the same frequency as Wave Y • Help! I don’t understand.

  5. Which of the waves in the picture has the greatest amplitude? 1 2 • 1 • 2 • 3 • Help! I don’t understand. 3

  6. Which property measures the amount of energy transferred by a wave? • Wavelength • Frequency • Amplitude • Help! I don’t understand.

  7. We are learning to demonstrate how waves transfer energy. We are looking for how waves interact with an object or other waves.  They either: Transmit-wave energy passes through an object. Reflect-wave energy bounces off an object. Refract – wave changes speed as it passes from one medium to another medium Diffract – wave spreads out as it passes through an opening or around the edge of a barrier Absorb-wave energy is taken in by an object they encounter. Interference-wave energy of multiple waves is combined.

  8. What happens to the energy of the wave when the crest of the blue wave meets the crest of the green wave? • Energy decreases. • Energy increases. • Energy stays the same. • I don’t get it! Help!

  9. What is it called when a wave bounces off of a barrier? • Refraction • Reflection • Diffraction • Help! I don’t know. 10

  10. What happens to waves as they go through an opening or around a corner of an object? • They are refracted. • They are reflected. • They are diffracted. • Help! I don’t know. 10

  11. As waves go through different mediums, what happens to them? • Waves change speed and are reflected. • Waves change speed and are refracted. • Waves change speed and are diffracted. • Help! I don’t know. 10

  12. We are learning to: demonstrate that vibrations produce longitudinal waves which move away from the original source. We are looking for: an explanation of the following: A medium is required (mechanical wave) A sound is produced (acoustic energy) A vibration is required to produce sound waves (longitudinal wave)

  13. Energy is required to create a sound wave. Sound energy is also known as . . . • Elastic potential energy • Radiant energy • Acoustic energy • Thermal energy • Help! I don’t understand.

  14. How does sound transfer energy? • By vibration of a medium, producing a transverse wave. • By vibration of a medium, producing a longitudinal wave. • By vibration of a medium, producing a surface wave. • Help! I don’t know.

  15. Sound cannot be heard in which of the following locations? • In a building • Under water • In space • In the forest • Help! I don’t know.

  16. For my records, Please Complete this Survey!! (so I know you reviewed)Thanks • https://docs.google.com/a/solonschools.net/spreadsheet/viewform?formkey=dGNKWFJJVGlfVmt6Z21KSlN5dzZheEE6MQ
