  1. Test Review

  2. Question #1 What determines the pitch of a note – its amplitude, frequency, or wavelength? DO NOT show your team’s answer until called upon to do so.

  3. Question #2 What determines the loudness or volume of sound– its amplitude, frequency, or wavelength?

  4. Question #3 What is an echo an example of – reflection, refraction, or diffraction?

  5. Question #4 What type of wave needs a medium to travel through – cosmic, mechanical, or electromagnetic?

  6. Question #5 What do waves transfer?

  7. Question #6 • If a wave is traveling at a certain speed and you cut its frequency in half, what would happen to the wavelength?

  8. Question #7 What happens when one wave runs into another wave and the crests overlap – reflection, diffraction, or interference?

  9. Question #8 What creates sound waves?

  10. Question #9 • What do we call the bending of a wave as it passes from one medium to another medium and its speed changes – reflection, refraction, or diffraction?

  11. Question #10 • What name is given to the number of waves that pass a given point in one second?

  12. Question #11 • The frequency produced by an object when it vibrates is called?

  13. Question #12 What do we call the frequency produced by an object when it vibrates?

  14. Question #13 What do we call the type of wave does not require a medium to travel through vibrates – longitudinal, electromagnetic, mechanical?

  15. Question #14 Which of the following are mechanical waves? Earthquake wave Radio wave Ocean wave Sound wave Light

  16. Question #15 Which of the following apply to sound waves? Mechanical waves Travel faster through a gas than through the air Travel in concentric circles Require a medium to travel through Travel as transverse waves

  17. Question #16 Complete the following: As wavelength gets longer, frequency becomes _________. As frequency becomes bigger, wavelength becomes ________.

  18. Question #17 Complete the following: As frequency becomes smaller, pitch becomes __________ As pitch becomes higher, frequency becomes _________.

  19. Terms Review Across 2. The ability of two or more waves to combine and form a new wave. 3. Crowded or dense area of a longitudinal wave 4. Lowest point of a transverse wave 6. This type of wave must have matter (a medium) to travel through; sound is an example 9. A rhythmic disturbance that carries energy through matter or space. 12. Highest point of a transverse wave interference compression compression Mechanical wave crest

  20. Terms Review Across 14. Less dense or “spread out” area of a longitudinal wave 16. The type of wave does not require a medium to travel through; light is an example 17. Number of wave crests or compressions that pass a point in one second 18. Type of wave in which the medium moves parallel (along with) the direction the wave is traveling rarefaction electromagnetic frequency longitudinal

  21. Terms Review Down Distance between two waves’ crests or two waves’ compressions 4. Type of wave in which the medium moves at right angles to the direction the wave is traveling 5. Wave bends as it hits a new medium; due to a change in the wave’s speed 7. Frequency produced by an object when it vibrates 8. Matter (gas, solid, or liquid) the wave is moving energy through wavelength transverse refraction Natural frequency medium

  22. Terms Review Down 10. Distance from the crest to the rest position (how tall is the wave) or how tightly a compression is squeezed 11. The highest or lowest of a note 13. Wave bends as moves around a barrier or through a hole 14. The transfer of wave energy from one system to another that vibrates at the same frequency (its natural frequency). 15. Wave bounces off a material and goes in a new direction amplitude pitch diffraction resonance reflection
