Sound Waves Flashcard

Front

What causes sound?

Back

Vibrations.

Front

What happens to the pitch of a sound as it approaches and then moves away from you?

Back

The pitch gets higher as it approaches, then lower as it leaves.

Front

What is the frequency of a sound wave?

Back

How often the wave repeats.

Front

What does the frequency of a sound wave affect?

Back

How high or low pitch it sounds.

Front

What does the amplitude of a sound wave affect?

Back

How loud or quiet the sound is.

Front

Define sound wave.

Back

A sound wave is a type of mechanical wave that propagates through a medium (like air, water, or solids) due to vibrations.

Front

What is pitch in relation to sound?

Back

Pitch is the perceived frequency of a sound; it determines how high or low a sound seems.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is amplitude in relation to sound?

Back

Amplitude is the maximum extent of a vibration or oscillation, which determines the loudness of the sound.

Front

How does sound travel through different mediums?

Back

Sound travels faster in solids than in liquids, and faster in liquids than in gases due to the density and elasticity of the medium.
