Students are using an electric fan to blow air over a pan of water to create waves in a pan. They record their observations in a data table. Which of the following can be concluded based on the student’s observations?

• The wavelength was affected by the speed of the moving air.

• The amplitude of a wave has an affect on its wavelength.

• Waves with a greater wavelength have a smaller amplitude.

• Air that moves more slowly produces waves with a lower amplitude.

Two students hold two ends of a rope. Student one moves one end of the rope up and down at a constant rate while Student 2 holds one end still. The students can increase the amplitude of the wave in the rope if-

• Student 1 moves the end of the rope more quickly.

• Student 1 moves the rope a greater distance.

• Student 2 and Student 1 move farther apart.

• they replace the rope with a longer one.
