  3. Topic 1 – 10 Points • QUESTION: • What do waves transfer? • ANSWER: • Energy

  4. Topic 1 – 20 Points • QUESTION: • Give an example of waves in every day life and why they are important • ANSWER: • May Vary

  5. Topic 1 – 30 Points • QUESTION: • Draw a wave that is getting louder • ANSWER:

  6. Topic 1 – 40 Points • QUESTION: • Draw a wave that has a decreasing pitch • ANSWER:

  7. Topic 2 – 10 Points • QUESTION: • What is frequency? • ANSWER: • The number of waves per second

  8. Topic 2 – 20 Points • QUESTION: • What unit do we measure frequency in? • ANSWER: • Meters/second or Hz

  9. Topic 2 – 30 Points • QUESTION: • How could I decrease the pitch of a guitar string? • ANSWER: • By removing your finger from the fret to increase the wavelength

  10. Topic 2 – 40 Points • QUESTION: • Demonstrate via your voice changes in frequency without changes in amplitude • ANSWER:

  11. Topic 3 – 10 Points • QUESTION: • Draw a wave with a frequency of 4 on the white board • ANSWER:

  12. Topic 3 – 20 Points • QUESTION: • With you group members using your arms demonstrate a wave with low frequency first and then a wave with high frequency • ANSWER: • (type answer here)

  13. Topic 3 – 30 Points • QUESTION: • Demonstrate a conversation with your group members demonstrating low amplitude • ANSWER: • Whisper

  14. Topic 3 – 40 Points • QUESTION: • Does amplitude affect the speed of a wave? Why? • ANSWER: • No, if you look at the equation, only wavelength and frequency will affect the speed of a wave.

  15. Topic 4 – 10 Points • QUESTION: • What unit do we measure wave speed in? • ANSWER: • Meters/second

  16. Topic 4 – 20 Points • QUESTION: • I have a wavelength of 15m and a frequency of 5 Hz. What is the speed of the wave? • ANSWER: • 75 m/s

  17. Topic 4 – 30 Points • QUESTION: • How can I increase the speed of a wave? • ANSWER: • Increase the frequency or increase the wavelength

  18. Topic 4 – 40 Points • QUESTION: • Which wave is traveling faster? • A. A wave with a wavelength of 10m and a frequency of 13 Hz • B. A wave with a wavelength of 5m and a frequency of 30 Hz • ANSWER: • (B)

  19. Topic 5 – 10 Points • QUESTION: • As the frequency of a wave increases what happens to the wavelength? • What kind of relationship is this? • ANSWER: • Decreases • Negative

  20. Topic 5 – 20 Points • QUESTION: • Draw a wave on the whiteboard that has an amplitude three times the wavelength • ANSWER:

  21. Topic 5 – 30 Points • QUESTION: • I have a wavelength of 4 m and a wave speed of 16 m/s. What is the frequency of the wave? • Hint: First write out the equation you are using • ANSWER: • Wavelength x frequency = wave speed • 4m x ? = 16 m/s • ? = 4 Hz because 4 x 4 = 16

  22. Topic 5 – 40 Points • QUESTION: • I travel in wavesOn the ocean shoreBut also everywhereYou have been beforeI am found in a shellAnd traveling through the airI am the soft purring of a catAnd the roar of a bearWhat am I? • ANSWER: • Sound
