Sound Waves
| Term | Definition |
|---|---|
| longitudinal | Sound waves travels as ________________ waves |
| vibrate | Sound is made when a source of energy forces the matter to _____________. |
| compression | A back-and-forth motion causing particles to move closer together generates a _______________. |
| apart | A rarefaction is generated when particles move ______________. |
| outer space | Sound waves can not travel through _________________. |
| solid | In this media, sound will travel the fastest: |
| vibrations | The elasticity of a substance describes how fast or slow its particles bounce back-and-forth as ________________ move through the object. |
| density | This physical property of a medium is defined by how close the particles of the substance are to each other. |
| cold | Is it HOT or COLD temperatures which causes sound to travel more slowly? |
| intensity, loudness, pitch | These are the three properties of a sound wave. |
| elasticity | This is NOT a property of a sound wave. |
| intensity | The amount of energy a sound wave carries per second through a unit of area is its __________________. |
| amplitude | The ________________ of a wave increases with increases energy. |
| decibles | Loudness of waves in measured in _________________. |
| 85 dB | This is the maximum safe level for loudness: |
| hertz | Frequency of waves is measured in ___________________. |
| high | High frequency sounds have a ________________ pitch. |
