If the energy of a sound wave is increased, what happens to the amplitude?

• As energy transfer increases, amplitude decreases causing sound to get quieter.

• As energy transfer increases, amplitude stops and no sound is made.

• As energy transfer is increased, the amplitude increases causing the sound to get louder.

• As energy transfer is increased, the amplitude remains the same, keeping the sound constant.

Which statement best describes the difference between electromagnetic and mechanical waves?

• Electromagnetic waves can travel through a vacuum. Mechanical waves must have a medium.

• Mechanical waves can travel through a vacuum. Electromagnetic waves must have a medium.

• An electromagnetic wave moves perpendicular to the direction of wave travel. A mechanical wave moves parallel to the direction of the wave's travel.

• An electromagnetic wave moves parallel to the direction of wave travel. A mechanical wave moves perpendicular to the direction of the wave's travel.

Which statement best describes the difference between longitudinal and transverse?

• Longitudinal waves transfer energy perpendicular to the direction of motion and a transverse wave transfers energy parallel to the direction of motion

• Transverse waves transfer energy perpendicular to the direction of motion and a longitudinal wave transfers energy parallel to the direction of motion

• Both transverse waves and longitudinal waves transfer energy perpendicular to the direction of motion

• Both transverse waves and longitudinal waves transfer energy parallel to the direction of motion

Why can sound NOT travel through a vacuum?

• A vacuum has no particles that are required to transport sound waves.

• A vacuum does not have enough particles to transport sound waves.

• A vacuum has too many particles that are packed too closely to transport sound waves.

• A vacuum has the incorrect type of particles to transport sound waves.

In the diagram shown, the red dot (source) is moving

• toward point B and away from point D

• toward point C and away from point A

• It is not moving. The source is stationary.

• toward point A and away from point C
