A sound wave - is a mechanical and a longitudinal wave, created by vibrations, Sound waves move - in all directions away from a source since it is causing the particles to move., Sound waves can travel - through air, but also liquid and solids., The density of the medium and temperature - affect the speed of sound too., Pitch - measure of how high or how low a sound is heard., Pitch depends on - the frequency of the sound wave., The higher the pitch, - the higher the frequency., The lower the pitch, - the lower the frequency., Loudness - how well a sound can be heard., The Doppler effect - change in frequency of a wave as its source moves in relation to the observer., Properties of Sound 1. - Depends on amplitude. , Properties of Sound 2. - Higher amplitude = higher energy = louder sound., Properties of Sound 3. - Measured in decibels (dB),
