Let’s see how much you’ve picked up with these experiments and the reading – answer as best as you can. (No peeking at the answers until you’re done!) Just relax and see what jumps to mind when you read the question. You can also print these out and jot down your answers in your science notebook.
Some of these questions you might recognize from the last lesson on potential energy, but we put them here again so you can see how they are inter-related. Have fun!

Section One:
1. What starts waves?
2. Where is work being done in a wave?
3. With the rope wave, what moved from partner to partner?
4. What is frequency?
5. What is Hertz?
6. If a swing is vibrating at .5 Hz, how many times does it go back and forth in 1 second?
7. If a yo-yo goes up and down 10 times in 10 seconds what is its Hertz?
8. If you create a rope wave by moving your hand up and down twice in one second, what’s the Hertz of that wave?
Section Two:
1. How does energy move?
2. True or false: the particles in a wave move from where the wave starts to where the wave ends up.
3. What is having work done on it in a wave?
4. What are the two type of waves?
5. In which wave does the particles vibrate in the same direction as the wave?
6. In which wave does the particles vibrate perpendicularly to the direction of the wave?
7. What does wavelength mean?
8. What does amplitude mean?
9. Which of the following has the longer wavelength?
10. Which of the following has the larger amplitude?
