Question

what is equation of a wave how we get it??show derivation

Answer 1

equation
y=acos/sin(wt-/+kx)

Answer 2

hw we get it?

Answer 3

what kind of wave? and you want a derivation without using differential equations I suppose?

Answer 4

twiddla?

Answer 5

um...
hold on let me try to prepare a simple answer first, I think I know what you want...

Answer 6

Answer 8

are you looking to get heena's answer, because I can only show
\[x(t)=A\cos(\sqrt{\frac{k}{m}}t+\theta_o)\]but I have to make the assumption that x will be a trig function of time. Otherwise I would have to use Differential equations. So basically I can only prove that \[\omega=\sqrt{\frac{k}{m}}\]does that help?

Answer 9

The Dirac equation or a Schrodinger equation... They won a Nobel Prize for their wave equations!
