I have experience with wave mechanics from a undergrad perspective, Modern Physics, etc.
I saw the statement the other day, "All waveforms are sinusoidal". I believe this to be not 100% correct.
Texts usually show a "nice" looking sine wave for most things "wave". I believe this is the starting point, for something that is usually more complex.
In the most simple terms, the up and down motion of any wave could be called "sinusoidal" correct?
From EE, I am aware of artificailly generated, Square, Triangle and Sawtooth Waveforms.
Would you say "most" waves, light, water, or otherwise are sine with added "harmonics" or funcitons?
Wiki seems to say there "IS" non-sinusoidal waves:
"Examples of non-sinusoidal waveforms include square waves, rectangular waves, ramp waves, triangle waves, spiked waves and sawtooth waves."
http://en.wikipedia.org/wiki/Non-sinusoidal_waveform
Would you call these "piecework" function waves?
Any "naturally occurring" examples of non-sinusoidal waves?
Impossible for light waves to be non-sinusoidal, correct?
