1. RS U2C1A7 Speed of Waves

2. Does the speed of waves depend on amplitude, frequency or something else? link to movie

3. Question 1 Does the larger amplitude transverse wave seem to move much faster, much slower, or at about the same as the speed as the smaller amplitude transverse wave?

4. Question 2 Does the larger amplitude compression wave seem to move much faster, much slower, or at about the same speed as the smaller amplitude compression wave?

5. Watch computer simulation of sound waves with the same frequency, but different amplitudes. link to movie

6. Question 3 Does the larger amplitude sound wave seem to move much faster, much slower, or at about the same speed as the smaller amplitude sound wave?

7. Question 4 Based on the three examples shown, does the speed of either a transverse or compression wave seem to depend on its amplitude? No, the speed of a transverse or compression wave does not seem to depend on its amplitude.

8. Does the speed of waves depend on amplitude, frequency or something else? link to movie

9. Question 5 Based on the three movie segments, do higher frequency waves (either transverse or compression) seem to move much faster, much slower, or at about the same speed as lower frequency waves? about the same speed Higher frequency waves (either transverse or compression) seem to move at about the same speed as lower frequency waves.

11. Question 6 Does the speed of the sound waves seem to depend on the medium (material) through which they move? Yes, the speed of the sound waves seems to depend on the medium (material) through which they move.

12. Question 7 Is the speed of sound in steel greater than, less than or the same as it is in air?

13. Question 7 The speed of sound in steel is greater than it is in air.

14. Which path can you run the fastest on?

15. Why does sound travel fastest in a solid?

19. Question 8 Show your work. What is the speed of the transverse pulse? Show your work. Speed

20. Question 9 How long does it take for the sound of the hammer strike to travel from one end of the steel beam to the other? Show your work.

21. Question 10 How long does it take for the sound of the hammer strike to travel the same distance through air (assume the temperature is 20°C). Show your work.

22. What have we learned: What property or properties of a wave determine its speed? (fastest in a solid and slowest in a gas). The speed of a wave depends upon the medium it moves in (fastest in a solid and slowest in a gas). The speed of a wave does NOT depend upon the wave’s frequency or amplitude..
