[Classical Waves] An elastic string with a mass per unit length of 0.0100 kgm–1 is attached to two posts separated by a 1.5 m. The string is tethered with a tension T = 0.230 N. Awave on the string is initiated at t = 0 such that a maximum amplitude of 0.150 m is first observedon the string at 0.0200 s and then 0.229 s later at the same point.A. Determine un(x,t) for this wave (Don't forget about the phase, p).B. Find the position(s) of any, and all, nodes of the wave at t= 0s at t = 0.650 s.

The time necessary for a particle to complete one cycle (for example, crest to crest) is called (a) velocity (b) period (c) wavelength (d) frequency
4) [swHW] It turns out that any function that has a finite number of finite-magnitude discontinuities and a finite number of extrema (maximums and minimums) over a finite interval can be represented exactly with an infinite series of cosine and sine functions called a Fourier Series. The conditions that the function must meet, called the "Dirichlet conditions", are not very restrictive, so most functions you will encounter in physics will have an associated Fourier Series. To give you a sense of how this is possible consider a very simple f(x) = x function on the interval -π
