Foucault’s experiment to measure the velocity of light

[Geocentric]

# Foucault’s experiment to measure the velocity of light supported:
1)Corpuscular theory
2)Wave theory
3)Photon theory
4)Electromagnetic wave theory

It cannot be Corpuscular theory because it said that the velocity of light in a denser medium is greater than that in a rarer medium. It however supported wave theory as it said that the velocity of light in a denser medium is less than that in a rarer medium. But the experiment does not support photon theory because we do not consider the particle nature of light. But I don’t know whether it supported the Electromagnetic wave theory. Could anyone clear my doubt?

I would go for just wave theory. There was no evidence that light consisted of an electromagnetic wave produced from that experiment. This was a discovery that came later.
