Brain Pop: Waves

What do seismic waves and sound waves have in common?

• They're mechanical waves

• They're electromagnetic waves

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

• Its frequency also increases

• Its moving through a denser medium

• Its wavelength gets longer

• It's carrying more energy

What medium do seismic waves travel through?

• Outer space

• The ground

What do waves carry from place to place?

• Energy, but not matter

• Energy and matter

• Matter, but not energy

• Neither energy or 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 returns to its original resting position

How are electromagnetic waves different from mechanical waves?

• Electromagnetic waves need a medium to travel through; mechanical waves do not.

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

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

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