A wave can make a leaf bob up and down on the water, but it cannot move the leaf toward the shore. This is because waves only transfer

• matter.
• energy.
• media.
• crests.

Which of these waves do NOT require a medium?

• ocean waves
• seismic waves
• sound waves
• radio waves

Which of the following is NOT a property of a wave?

• refraction
• amplitude
• frequency
• wavelength

When two objects, such as marimba bars and columns, vibrate at the same frequency, this occurs.

• refraction
• reflection
• resonance
• amplitude

If a wave is traveling at a certain speed and you cut its frequency in half, what would happen to its wavelength?

• The wavelength would be halved.
• The wavelength would produce a standing wave.
• The wavelength would remain the same.
• The wavelength would be doubled.

How do waves transfer energy?

• through ocean waves
• by the vibration of particles in a medium
• through compression
• by a combination of waves

A section of a longitudinal wave where the particles are crowded together is called a

• rarefaction.
• compression.
• vibration.
• surface wave.

When the crests of one wave overlap the crests of another wave or waves, this occurs.

• diffraction
• destructive interference
• constructive interference
• resonant frequencies

the number of waves produced in a given amount of time

• frequency
• wavelength
• wave speed
• amplitude

the speed at which a wave travels through a medium

• frequency
• wavelength
• wave speed
• amplitude
