The picture shows the path of a sound wave as it moves from left to right. What has taken place at point X to change the sound wave?

• The sound wave has run out of energy and turned into a slower light wave.

• The sound wave has gained energy and turned into a faster light wave.

• The sound wave has moved into a new material and slowed down.

• The sound wave has moved into a new material and sped up.

A substance that carries sound waves is called

• a fulcrum

• a medium

• a spectrum

• an equilibrium

Which statement correctly describes how a sound wave travels through air?

• The wave carries molecules of air away from the source of the sound.

• The wave carries energy that causes molecules to move back and forth.

• The wave carries a molecule in one direction until it collides with another molecule.

• The wave moves through the air and gains energy from the moving molecules that it touches.

Derick plays the trombone in band class and he can hit a perfect "A note", according to his teacher. Derick can hit an "A note" by blowing very soft or by blowing very hard. By changing how hard he blows into the trombone, Derick is changing how loud the note is. Which property of waves is he changing when he changes how loud the "A note" is?

• wavelength

• direction

• frequency

• amplitude

Number 1 represents the

• Wavelength (corresponds to rate/frequency of the wave)

• Amplitude (corresponds to energy/volume)
