| Question | Answer |
| Sound waves are made up of | chains of vibrating molecules |
| sound moves in a | longitudinal wave |
| A compression is a | High-pressure area of tightly packed molecules |
| A cycle is created by | a combination of a compression and rarefaction |
| oscilloscope | Measures sound waves |
| A rarefaction is a | Low-pressure area of loosely packed molecules |
| The reflection of sound waves off a hard surface can create an | echo |
| Soft surfaces.... sound waves | absorb |
| amplitude measures | the force of a compression and describes how loud a sound is |
| Pitch is determined by sound waves | Frequency |
| temperature affects the.... of sound waves | Speed |
| Sound waves travel farther through... media, such as water or steel | Dense |
| a series of compressions an d rarefactions traveling through a medium | sound wave |
| The height of a wave | amplitude |
| A measure of how many times an object vibrates per second | frequency |
| using echoes to find a location | echolocation |
| the unit in which sound Is measured | Decibel |
| how high or low a sound is | pitch |
| What boats use to locate objects under water | sonar |
| How loud or quite a sound is | volume |
| A change in pitch of sound when it starts to move towards or away from you | Doppler effect |
| A region of empty matter through which sound cannot travel | Vacuum |
| A sound wave that bounces off a surface | echo |
| The material through which a sound wave travels | Mediums |
| Speed of sound waves depend on.. | type of medium/density |
