Physical examples of periodic phenomena
Name: mike n vaughn
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
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.
