Longitudinal Waves and Sound Flashcard 2025

Front

Sound is transmitted by _____________.

Back

longitudinal waves

Front

A low amplitude means ....

Back

The sound is quieter

Front

Which wave has the highest frequency?

Back

3

Front

If the frequency is higher, then....

Back

The pitch is higher

Front

Sound waves require a medium because .....

Back

Sound is just vibration. Without particles to vibrate, sound doesn't exist.

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium move parallel to the direction of the wave's energy.

Front

What is amplitude in sound waves?

Back

The maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

What does frequency measure in sound?

Back

The number of waves that pass a point in one second, measured in Hertz (Hz).

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 the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.
