Study Notes
Sound Waves
- Sound is produced by vibrations
- The major requirement for sound production is vibration
- Vibrations cause compressions and rarefactions
- The tuning fork, string, drum skin, and a person's vocal cords produce sound
- The loud speaker creates sound with the vibrations from the cone
- Sound waves are longitudinal waves
- Sound travels through a medium (solid, liquid, or gas)
- Sound cannot travel through a vacuum
- The direction of vibration is parallel to direction of wave movement
- Sound waves move through the air as longitudinal waves, thus causing alternating compressions and rarefactions in the air
- When the diaphragm moves outward, a compression forms.
- When the diaphragm moves inward, a rarefaction forms.
- Sound is produced by the loud speaker in a diaphragm movement
- These compressions and rarefactions move through the air, causing the flame to move forward and backward
- The particles get closer to each other when a compression happens, they spread out during rarefaction.
- Sound waves travel faster in a medium where the particles are closer together.
