Sound Wave Characteristics Flashcard

Front

What type of wave are sound waves?

Back

Sound waves are longitudinal waves.

Front

Why are there no sounds in space?

Back

There are no sounds in space because there is not enough matter to carry sound waves.

Front

What happens to sound when the amplitude increases?

Back

The sound becomes louder.

Front

What happens to sound when the frequency decreases?

Back

The sound has a lower pitch.

Front

If Wave A has a taller amplitude than Wave B, what can be said about their loudness?

Back

Wave A is louder than Wave B.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency means higher pitch, while lower frequency means lower pitch.

Front

What is amplitude in relation to sound waves?

Back

Amplitude refers to the height of the wave, which determines the loudness of the sound.

Front

What is the speed of sound in air?

Back

The speed of sound in air is approximately 343 meters per second at room temperature.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave.
