Circle the answer.

1. 1.

   A student claims bigger waves are always longer waves. Which example proves this wrong?

   • a short wave with crests close together
   • two waves with crests 5 cm apart, one taller than the other
   • a tall wave with crests far apart
   • two waves that are exactly the same
2. 2.

   A student holds a rope and moves her hand up and down faster. The crests get closer together. What changed?

   • the wavelength got shorter
   • the wavelength got longer
   • the amplitude got bigger
   • the rope got longer
3. 3.

   Two tuning forks make the same note. Fork A is struck harder. What will a listener notice?

   • fork A sounds the same
   • fork A sounds quieter
   • fork A makes a light flash
   • fork A sounds louder
4. 4.

   Kim measures waves in a tray: crest to crest is 3 cm, and height above the middle is 1 cm. What are the wavelength and amplitude?

   • wavelength 4 cm, amplitude 1 cm
   • wavelength 3 cm, amplitude 1 cm
   • wavelength 3 cm, amplitude 3 cm
   • wavelength 1 cm, amplitude 3 cm
5. 5.

   During an earthquake, waves travel through the ground. What do they carry from place to place?

   • rocks from the center of Earth
   • energy that shakes the ground
   • the soil from where they started
   • water from the ocean
