Wave forumla: y(x,t) = Asin(kx-wt)  Which variables (x, t, A, k, w) are independent? Would k be the only independent variable since it is a constant? However I am not too sure what exactly does the k represents. Can someone please clear that up for me?  Which of the following are parameters that determine the characteristics of the wave? x only, t only, A only, k only, w only, x and t, w and t, A and k and w. Would A and k and w determine th characteristics of the wave? I know that A is the amplitude of the wave and w is the angular frequency of the wave so those 2 has to be characteristics of the wave.  What is the phase of the wave? That would be (kx-wt) right?  What is the wavelength of the wave? Would that be 2pi/k?  What is the period of this wave? Would that be 2pi/w?  How do I find the speed of propagation v of this wave? Thank you for your help.
