How does amplitude affect the loudness of a sound?

• Lower amplitude results in a louder sound.

• Amplitude has no effect on the loudness of a sound.

• Amplitude affects the pitch of a sound, not the loudness.

• Higher amplitude results in a louder sound.

What are sound waves and how do they relate to vibrations?

• Sound waves are vibrations that travel through a medium and our ears detect them as sound.

• Sound waves are vibrations that travel through water and our skin detects them as sound.

• Sound waves are vibrations that travel through the air and our eyes detect them as sound.

• Sound waves are vibrations that travel through solids and our ears detect them as sound.
