P201 (2/10/2011) Sound : mechanical energy (longitudinal wave). (with sound your pushing air back and forth). Sound Wave : Periodic wave form: (Have focused pitch) (repeating pattern). Smallest part of the pattern that repeats is called 1 Cycle. Frequency : # of cycles per sec. (cps) cycles/sec (frequency is the INVERSE of Period. Period : Time it takes for 1 cycle to elapse, sec/cycle, Period is the INVERSE of frequency. Wave length: speed of sound/freq. Can use Google Calculator for test or bring your own.
