particles move parallel (side to side) to the direction the wave travels

• longitudinal wave

• transverse wave

• a wave drawn with my pencil

• a squigly line

What is the wavelength of this wave?

• 1.5m

• 3.0m

• 5.0m

• 6.5m

What is frequency?

• The number of waves that pass a given point in one second.

• The distance measured from a crest to a crest or trough to trough.

• The distance from a trough to a crest

• The distance from the resting point to the top of a crest or bottom of a trough.

Which term describes the number of waves passing a point during a certain period of time?

• Crest

• Frequency

• Range

• Wavelength

A local surf report provides the height of the wave from the trough to the crest of the wave. How does this relate to the wave’s amplitude?

• It is less than the wave’s amplitude.

• It is equal to the wave’s amplitude.

• It is about twice the wave’s amplitude.

• It is about half of the wave’s amplitude.

• frequency

• wavelength

• wave speed
