| sound | vibrations you can hear |
| compression | the part of a sound wave where air is pushed together |
| sound waves | quickly moving areas of high and low pressure in matter that creates and carries the sound |
| amplitude | a measure of the energy a sound wave carries (the height of the wave) |
| wavelength | the distance in a straight line from one ripple of a wave to the next |
| wave peak | the compressed, high pressure area of a wave pattern |
| wave valley | the lowest points or low pressure areas of a wave pattern |
| loudness | the measure of the strength or amount of sound energy reaching your ears |
| pitch | a measure of how high or low a sond is. It is dependent on how fast the sound wave is vibrating |
| speed of sound | the speed at which a sound travels |
| echo | a sound reflection |
| sound absorption | the ability of some matter to muffle or stop sound |
| sonic boom | the loud sound a plane makes when it compresses the sound waves in front of it by travelin faster thn the speed of the sound |
| kinetic energy | the energy that sound transfers as it moves through the air |
| transverse wave | a wave in the ocean |
