Sound Waves Description Light waves are transverse waves. Sound waves are longitudinal waves.
Relating the Two Wave Types Variations in Air Pressure and Corresponding Waveform
Wave Properties and Sound A large amplitude = loud sound Areas of compression are wide. A high frequency = high pitch Areas of compression are close together.
Sound Waves and Instruments To make sound, musical instruments vibrate. Vibrations from the instrument cause the longitudinal waves to form. The frequency and size of the vibrations determine the pitch and volume of the sound.
Musical Instruments How they work… A wave is made and then amplified within the instrument. Woodwinds The reed makes the wave. Brass Your lips make the wave. String Plucking a string makes the wave. Percussion Hitting the drum makes the wave.
