Do waves transfer matter?

• No, waves transfer energy

• Yes, they sure do!

The slinky was used to demonstrate

• transverse waves

• longitudinal waves

• both longitudinal and transverse waves

Why does the salt on the speaker vibrate when the music is turned on?

• The sound waves cause the salt to vibrate just like the air

• Salt really likes all kinds of music!

Sound waves can't move through a vacuum.

• False. That was magic.

• True. Sound waves can't travel through a vacuum.

When the waves have a repeating pattern of compression and expansion.

• longitudinal wave

• Pacific Ocean

• transverse wave

• sound wave

The ocean's waves are examples of

• transverse waves

• a vacuum

When you add more energy to a transverse wave, the waves get

• higher and lower

• muddy

• saltier

The distance between the peaks of a wave is the

• wavelength

• corner store

• amplification

Adding energy to a transverse wave causes the

• height (amplitude) of the wave goes up.

• wavelength to get smaller, the distance is shorter.
