Students on a playground are not able to hear their teacher's whistle. They decide to test three new whistles to identify a whistle they can hear. They use a special app on a cell phone placed 3 meters away from the whistle to examine the sound waves from each whistle. Figure 1 shows the height of each sound wave. Picture 2 shows the spacing between each wave peak. What do you notice is true about whistle 2.

• Whistle 2 is loudest.

• Whistle 2 made the ball roll the farthest.

• Whistle 2 has the highest frequency.

• Whistle 2 has the highest amplitude.
