sound waves *a compressional wave produce by vibrations in matter *sound travels at different speeds in different materials *move slowest in gases and fastest in soilds
Pitch pitch describes a sound. pitch depends on the sound waves frequency or how many waves pass a point 1 second . highness and lowness describe pitch. high number of waves = high pitch ,low number of waves = low pitch.
Doppler effect an increased ( or decrease ) in frequency of sound waves the source and observer move toward ( or away from ) each other. the effect causes the sudden change in pitch noticeable in passing siren or plane
wave a disturbance that transfers energy from one point to another
