this is a much more complicated question than perhaps you realise. try looking up "wave particle duality" photons have the strange characteristic of haveing properties of both a wave and a particle.
yes it supports the wave theory of light...
It is the wave theory of light that best explains interference. The particle theory has problems when applied to this observable phenomenon.
Light ray theory and shadows. Basically the light ray theory is the theory that light always travels in straight lines, and it is linked into shadows as when an object blocks the light rays it cannot bend round the object therefore making a shadow.
Particle theory of light can explain Photoelectric Effect,Compton effect,Pair production.... wave theory of light can explain interference,refraction...
The speed of light is a number. It was a theory before it was measured. After it was measured, and the prediction was found to be correct, it was no longer a theory nor a hypothesis. It became a "physical constant".
It isn't clear what theories you are talking about.
Christian Huygens' was one of the first to suggest that light was a wave. His theory, the wave theory of light, stated this, it was opposed by Newton's idea that light was a particle. More recently, scientists such as Thomas Young and Max Planck proved this theory with experiments. So, simply put, the wave theory states that light is a wave, which, as far as we know, is correct.
A theory becomes a law when it is tested and found to be true for the way things happen. One is the Newtonian physics theory, which is mostly correct but has been superseded by relativistic physics. The difference comes when measurements are taken at a fraction of the speed of light. Another example is the belief that the earth is flat.
the evidence that the phlogistan theory was correct was that there was heat and by the way this is definetly correct
The most modern theory of light is the quantum theory.
compound light microscope - cell theory - electron microscope
The correct spelling is 'theory'.

By performing experiments whose goal is to prove that such theory is a mistaken theory.
Economic Theory
That theory states that light behaves as group of particles.
