Direction of particles in a longitudinal wave

For this question the answer key says it is A. However I think it should be B. At T=0 the particles will be headed towards the node. Given that the equillibrium points happen when T=T/4 it would make …

Human error in wave experiment

I am trying to see what the fundamental frequency of a string is by slowly increasing the frequency on a function generator. This experiment relies on the experimenter to record the frequency as soon …
