Waves Scavenger Hunt

Name:

Hour:

You may use your textbook or notes to answer the following questions (front and back), but you must work alone and your answers must be written in your own words. Some of this we might not have covered yet, but you can easily find the answers in your book, pages 363-373.

1. What is the top of a wave called?

2. What is the bottom of a wave called?

3. What is frequency?

4. If a wave is traveling at 60 cm/second and has a wavelength of 15 cm, what is the frequency?

5. What does amplitude measure?

6. On the diagram below, indicate with an arrow the distance that represents the wavelength of the wave. With another arrow indicate the distance that represents the amplitude. Try to label other parts of this wave.

7. How many complete waves are there in the diagram above? Is it transverse or longitudinal?

8. What is the difference between a transverse wave and a longitudinal wave?

9. Are sound waves transverse waves or longitudinal waves? Why?

10. Why can’t you calculate the frequency of the wave in the diagram on the other side of the page? What information is missing?

Try some of these math problems involving frequency and wave speed. (v = f λ)

11. The average wavelength in a series of ocean waves is 15.0 m. A wave arrives

every 10 s, so the frequency is 0.100 Hz. What is the average speed of the wave?

12. A wave along a guitar string has a frequency of 440 Hz and a wavelength of 1.5

m. What is the speed of the wave?

Writing: Use your books to discover the Doppler effect. Form a well written paragraph or two describing what it is and where you have experienced it.
