approximations of the laws of nature. Faraday's empirical relations
have turned out to be very broad. Einstein extended them into the
realm of charges moving at high speed.
Einstein performed no experiments involving charge moving at high speed.
He made assumptions and did the maths.
These relationships of Faraday seem to me very basic, indeed.
Maxwell basically added only one term to them, the term for
displacement current.
You might be interested in this. An article called "Displacement current and how to get rid of it"
http://www.electromagnetism.demon.co.uk/z001.htm
With that addition, the relationships ended up
explaining light.
You might be interested in the following article which explains that Maxwell's equations could be describing the motion of a plank:
http://www.ivorcatt.com/2804.htm
It concludes "So the only information about electromagnetism contained in the apparently sophisticated equations [Maxwell's] (9) and (10) is about the two constants in electromagnetism: the fixed velocity c, and that E, H at every point are in fixed proportion Zo. The remaining content of Maxwell's Equations is hogwash."
The laws of optics can be derived from Maxwell's
equations,
Can they? I rather think not.
which as you pointed out are mostly Faraday's equations.
Faraday was a very smart guy.

"By making the key discoveries of their era, uneducated technicians like Michael Faraday and James Watt threatened the scholastic myth, that all progress, including scientific progress, needs must use the rigour and discipline controlled by academics in places like Cambridge University.
The ultimate in scientific rigour (rigor mortis?) was held to be mathematics. Biography and History of Science writings spawned in academia present the thesis that, lacking mathematics, Faraday could not and did not really effect his discovery of electromagnetic induction. Rather, he stumbled into it, but it could only be properly exploited decades later, after Professor Maxwell had placed a mathematical structure upon Faraday's fumbling, unscholarly ideas. Thus, according to the Platonic interpretation of history, Professor Maxwell, not Faraday the technician, paved the way for massive exploitation of electromagnetism in transformers, motors and generators. The deeper message in Maxwell's Equations is that, do what they will, the local yokels will not replace mathematical academia as the fount of knowledge and progress."
Just because I keep on saying
"Maxwell's equations" doesn't mean I don't know who Faraday is. Just
as when I talk about Newtonian physics, I remember full well that most
of these relations came from Galileo. What does the name of the author
have to do with the fundamental nature of the equations themselves?
More important: who the Halifax is Dr. Scott Murray?
"Dr Scott "Sandy" Murray retired from the British Scientific Civil Service in 1982. Having served in the Royal Navy during the second half of World War II, he took a first degree with honours in physics at Manchester under P. M. S. Blackett and a second in radio astronomy. In the course of obtaining the first UK radar echoes from the moon at Jodrell Bank, he discovered the Faraday rotation of radio waves in the ionosphere. He joined the Royal Radar Establishment in 1954, where the most enjoyable of his tasks was designing, and for ten years directing, the 45ft Malvern satellite tracking radar. That project itself was one consequence of a joint experiment with the Post Office, in which the first-ever transatlantic satcom signals were received in England via Echo 1; its other consequence was the Goonhilly Downs station."
