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

• It continues moving forward with the energy

• It breaks apart into its basic atoms

• It returns to its original resting position

• It bonds with the molecule next to it

How are electromagnetic waves different from mechanical waves?

• Only electromagnetic waves need a medium to pass through

• Only electromagnetic waves can pass through water

In what direction is matter displaced in a transverse wave?

• In the same direction as the energy flow

• In the opposite direction as the energy flow

• In a spiral around the energy flow

• At a right angle to the energy flow

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

• It has a low frequency, like thunder

• It has a high frequency, like a whistle

• It has a high amplitude, like loud music

• It has a low amplitude, like a gentle rain
