| sound is a form of | energy |
| sound is caused by | vibration |
| the energy of the vibration travels as a | sound wave |
| a sound wave is this kind of wave | longitudinal |
| all sound waves require this (hint: solid/liquid/gas) | medium |
| the closer the molecules are to each other the _____ the sound wave can travel | faster |
| sound waves travel the fastest in this medium | solids |
| sound cannot travel in this | a vacuum |
| this is how high or low a sound is (hint: musical note) | pitch |
| this is how loud or soft a sound is | volume |
| pitch depends on the | frequency |
| volume depends on | the amount of energy |
| frequency | is the speed of vibration and is measured in HERTZ |
| a high frequency gives a | high pitch |
| volume is measured in | decibles |
| greater amplitude equals | louder sound |
| pitch depends on | how fast an object vibrates per second, frequency, and wavelength |
