Amplification factor r(k) for spinodal decomposition has the following dependence on wave vector k: r\left ( k \right )=-lk^2((\frac{d^2g}{dx^2})_x=_x_0+ 2kk^2)
find the value of km corresponding to the fastest growing wavelength (related to a maximum of r). connect it with kc - critical wave number for start of spinodal decomposition (r(kc)=0). give qualitative explanation why km
