Waves X and Y are moving through identical materials. When wave X moves through the material, the particles in the material move up and down. When wave Y moves through the material, the particles in the material move from to side. What can be determined about the waves?

• Wave X is a longitudinal wave and wave Y is a longitudinal wave.

• Wave X is a transverse wave and wave Y is a longitudinal wave.

• Wave X is a longitudinal wave and wave Y is a transverse wave.

• Wave X is a transverse wave and wave Y is a transverse wave.

Which of the following would be the best demonstration of a longitudinal wave?

• Turning a flashlight on and off.

• Squishing and stretching a spring.

• Swinging a rope back and forth.

• Moving a rock up and down.

A student creates a graph of position v. time for the height of a floating buoy as ocean waves go by.

What is the amplitude of the buoy based on the graph?

• 2.0 m

• 2.5 m

• 5.0 m

• The amplitude varies depending on the time.
