[SOLVED] standing waves 1. The problem statement, all variables and given/known data A standing wave is a superposition of two harmonic waves described by y1= Asin(kx+wt) and y2= A sin(kx-wt), where A=3.31594 cm, k=10.0531 m-1, and w=18.2212 s-1. Determine the smallest positive value of x correspoding to a node. So i added the two waves together and got y=2Asin(kx)cos(wt). I set y=0 and tried solving for x but i just got zero which was incorrect. Can someone help me solve these types of problems. Thanks.
