Circle the best answer, or write your answer on the line.
A rope wave's crest is 3 squares above the rest line on a grid. Each square stands for 10 cm. What is the amplitude, Ari?
A water ripple's crest is 2 squares above the rest line on a grid. Each square stands for 5 cm. What is the amplitude, Bo?
A rope wave's crest is 4 squares above the rest line on a grid. Each square stands for 2 cm. What is the amplitude, Esme?
In the wave graph, which letter marks a crest, Jun?
- B
- C
- A
In the wave graph, what is the amplitude, Kira?
Use the picture in question 4.
- 60 cm
- 30 cm
- 80 cm
In the wave graph, which arrow shows the amplitude, Luz?
Use the picture in question 4.
- C
- D
- An arrow from a crest down to a trough
A rubber duck floats on a pond as ripples pass under it. What does the duck do, Milo?
- Rides the ripples to the far edge
- Bobs up and down in about the same spot
- Sinks under each crest
Noah ties a ribbon to the middle of a rope and sends a wave along it. What does the ribbon do?
- Travels to the far end of the rope
- Stays still the whole time
- Moves up and down, then is back where it was
Sound travels from a drum to Pia's ears. What travels across the room?
- Energy, passed along by vibrating air
- The same air, from the drum to the ears
- Tiny bits of the drum
Zee drops a big stone and a small pebble into a pond. Which makes taller ripples?
- Neither; ripple height has nothing to do with energy
- The pebble, since small things make big waves
- The big stone, which gives more energy
