Why would surfers prefer a set of waves with higher frequency? Identify the BEST explanation.

• They have more energy and will last longer.

• They have less energy, but will last longer.

• They have more energy and there are more opportunities to "catch a wave."

• They have less energy, but there are more opportunities to "catch a wave."

Fans at the superbowl with young children place noise-cancelling headphones on them to protect their hearing. Which of the following statements BEST explains why this is a wise move?

• The headphones actually do nothing, but they look cute.

• The headphones protect from the high amplitude of the noise.

• The headphones protect from the long wavelengths of loud noise.

• The headphones prevent the child from hearing any sound so that they are not startled.

How could surfers estimate the amplitude of waves coming in to shore?

• Count how many waves are in a set.

• Mentally measure how long (in distance) each wave is.

• Look at the horizon and mentally measure how tall the waves are.

• Check to see if the waves are breaking near the horizon.
