WHAT SHE WANTED
"The sea pronounces something, over and over, in a hoarse whisper; I cannot quite make it out." ~Annie Dillard, via QuoteGarden.com.
There are many wave type motions. Ocean waves, sound waves, light waves, radio waves, waves on strings.
But what exactly is a wave? Einstein and Infield, in their book The Evolution of Physics, describe a wave in this way: "The wind passing over a field of grain, sets up a wave which spreads out across the whole field. Here again we must distinguish between the motion of the wave and the motion of separate plants, which undergo only small oscillations....The essentially new thing here is that for the first time we consider the motion of something which is not matter, but energy propagating through matter."
