WAVES

What do seismic waves and sound waves have in common?

• They're mechanical waves.

• They're electromagnetic waves.

• They're phonetic waves.

• They're permanent waves.

What does it mean when a wave's amplitude increases?

• Its frequency also increases.

• It's moving through a denser medium.

• Its wavelength gets longer.

• It's carrying more energy.

What medium do seismic waves travel through?

• The air

• The ground

• Water

• Outer space

What do waves carry from place to place?

• Energy, but not matter

• Energy and matter

• Matter, but not energy

• Neither energy nor matter

In a wave, what happens to a molecule after it passes energy on to the next molecule in the chain?

• It continues moving

• It vibrates rapidly from the buildup of energy

• It becomes completely still

• It returns to its original resting position

How are electromagnetic waves different from mechanical waves?

• Electromagnetic waves need a medium to travel through; mechanical waves don't.

• Electromagnetic waves can travel through water; mechanical waves can only travel through solid matter.

• Electromagnetic waves can travel through empty space; mechanical waves can't.

• Electromagnetic waves are long chains of vibrating molecules; mechanical waves aren't.

Which of the following are electromagnetic waves?

• Water waves.

• Radio waves

• Sound waves

• Seismic waves

What type of waves carry energy at a right angle to the direction of the energy flow?

• Compression waves

• Transverse waves

• Sound waves

• P-waves

How is wavelength measured?

• 
• 
• 
• 

What can you infer about a wave with a short wavelength?

• It has a low amplitude.

• It has a high amplitude.

• It has a high frequency.

• It has a low frequency.
