Hi all,
In all books I looked it is written that energy carried by a wave is proportional to its amplitudes square
i.e.
E[tex]\propto[/tex]A2, if wave equation is f(x)=Asin(wx)
but what is the exact equation?
Also if we define the wave with Fourier series
f(x)=[tex]\sum[/tex]Acos(nx)+Bcos(nx)
what would be the energy carried by this wave?
