    Common nodes of several waves

    I am interested in the number of common nodes on the x axis of two sinusoidal waves y1 = sin (a1 x + b1) and y2 = sin (a2 x + b2) on a certain distance D from the origin. Can one write a generalized formula for more than two waves?

    Charmonium, nodes and turning points

    Hi everyone, Considering charmonium's radial wavefunction, what is the relationship between the number of nodes and turning points and the principal and orbital angular momentum quantum numbers, n & l? For example, in some bound energy state of charmonium with: principal quantum number n...
