I am looking for natural or man-made examples of periodic phenomena. My precalculus class has completed a unit on analyzing graphs of trig functions, and I wish to assign them to complete a research paper on one particular type of periodic occurence. We have discussed tidal motion, electricity (AC), biorythyms, EKG's, simple harmonic motion, planetary motion, etc. Anything you can add to the list will be appreciated.

Sound, especially music and 'pure' tones. All forms of electro-magnetic radiation, from gamma rays to x rays to ultraviolet, visible light, infrared, microwaves, and radio frequencies.


Springs. Pendulums. Car engines.
