    Two wave superposition with different wavelength , amplitude and frequ

    I think i found a way to solve it so if i make two vectors where A1 and A2 is the module of each vector I just have to sum them and then find the angle of the resulting vector. Where θ1=k1x-w1t θ2=k2x-w2t u1=A1cosθ1 u2=A2cosθ2 And alfa=(θ1-θ2)/2+θ2=θ1+θ2/2

    Two wave superposition with different wavelength , amplitude and frequ

    Expresing in terms of A=√A21+A22 I arrive to the expresion u(x,t)=(A/sinθ)(tan(θ)cos(k1x+w1t)+cos(k2x+w2t)) I dont see how it can help :/ but thanks Maybe I can prove that theres a Amplitude modulation without merging the cos
