I have a question on "k" of an armonic simple movement.(adsbygoogle = window.adsbygoogle || []).push({});

If we take the equation of a wave, this is:

[tex] \frac {\partial \psi (x,t)}{\partial x^2} = \frac 1 v^2 \frac {\partial^2 \psi (x,t)}{\partial t^2} [/tex]

And this, if I'm not wrong, must to satisfy the independent of time Helmholtz equation:

[tex] \frac {d^2 A(x)}{dt} + k A(x) = 0 [/tex]

I'm ok since here?

If it's ok, the solution of the first equation could be:

[tex] \psi (x,t) = A e^{kx-wt} [/tex]

Is this "k" the same that the "k" in Helmholzt equation? Is there any mistake in this?
