SUMMARY

The discussion confirms that Maxwell's equations demonstrate the wave nature of electromagnetic waves, specifically through the derived wave equation for the electric field, \nabla^2 E=\mu_0 \epsilon_0 \frac{\partial^2 E}{\partial t^2}. This equation establishes that electromagnetic waves propagate at a velocity of v = 1/√(µε). The conclusion is definitive: the wave velocity of electromagnetic waves is indeed proven by Maxwell's equations.

the general wave equation has form [itex]\nabla^2f=\frac{1}{v^2} \frac{\partial^2 f}{\partial t^2}[/itex]

is proving using Maxwell equations that the electric field satisfies a wave equation of the form [itex]\nabla^2 E=\mu_0 \epsilon_0 \frac{\partial^2 E}{\partial t^2}[/itex] sufficient to show that the wave has velocity v?

I would say so.
 
Yes, that would show that electromagnetic waves have speed 1/√(µε).
