I've been told that, from Maxwell's equations, one can find that the propagation of change in the Electromagnetic Field travels at a speed 1√μ0ϵ0 (the values of which can be empirically found, and, when plugged into the expression, yield the empirically found speed of light)
I'm really not sure how I would go about finding v=1√μ0ϵ0 simply from Maxwell's equations in the following form, in SI units --
∇⋅E=ρϵ0
∇⋅B=0
∇×E=−∂B∂t
∇×B=μ0(J+ϵ0∂E∂t)
Is what I believe true? (that the speed of propagation is derivable from Maxwell's Equations)
If not, what else is needed?
If so, can you provide a clear and cogent derivation?
