I am losing my mind over this, it seems the longer i think about it the further i get from a definitive answer. It started with me trying to understand the variables the would result in a standing wave, ie: what needs to occur, why, and how it occurs. At first i was confused because it seemed that the normal force at the fixed end should just halt all motion since it is an application of dampening but i was told that something happens which distorts the reflected wave in some way? Im not sure what could be happening to distort the wave. Second, I dont understand how exactly the reflected wave is created in the first place, like i said above it seems to me that the energy should just be dissipated at the fixed end by the normal force not reflected upside down. The last concept im just unsure about, I did some quick math with a simplified wave force diagram and it seems that the nodes could only be located were the two opposing waves first intersect, but that would mean you could generate nodes even if the reflected wave didnt math the energy of the incident wave? Any help would be greatly appreciated I've spent days obsessing over this and i get too fixated to just move past it and finish the chapters.
