"Maxwell's Theory of light is not based only on Faraday's Law"
I don't understand this statement, perhaps you made a miss spelling or something.

The general equations are next applied to the case of a magnetic disturbance propagated through a non-conductive field, and it is shown that the only disturbances which can be so propagated are those which are transverse to the direction of propagation, and that the velocity of propagation is the velocity v, found from experiments such as those of Weber, which expresses the number of electrostatic units of electricity which are contained in one electromagnetic unit. This velocity is so nearly that of light, that it seems we have strong reason to conclude that light itself (including radiant heat, and other radiations if any) is an electromagnetic disturbance in the form of waves propagated through the electromagnetic field according to electromagnetic laws.
From his link:Heaviside did much to develop and advocate vector methods and the vector calculus. Maxwell's formulation of electromagnetism consisted of 20 equations in 20 variables. Heaviside employed the curl and divergence operators of the vector calculus to reformulate 12 of these 20 equations into four equations in four variables (B, E, J, and ρ), the form by which they have been known ever since (see Maxwell's equations).
SteveB...........We seem to agree that Maxwell's electromagnetic theory of light is based on induction, right. Therefore, how do you justify using induction, that is not optical, to represent the electromagnetic field structure of light, in Maxwell's electromagnetic theory of light?
The derivation of the EM wave equations of light, using Maxwell's equations, cannot be justified since the expansion method directly contradicts the divergent method.

For anyone interested, a live lecture is sometimes easier to follow than a book.

Yes, the first 30 minutes is what I intended to be of interest. You may have noticed the sign error in Maxwell's equation. He picks up on this at the end of the lecture, but it does not affect the basics of the wave equation discussion.
