Isaac newton's theory that light is composed of particles called corpuscles was later proven to be incorrect. James Clerk Maxwell's theory that light is an electromagnetic wave was ultimately validated by experiments and is accepted as the correct explanation for the nature of light.
One of Albert Einstein's theories that has been proven correct is the theory of general relativity. This theory describes gravity as a curvature in space and time caused by mass and energy, and it has been confirmed through various experiments and observations, such as the bending of light around massive objects like stars.
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.
The correct abbreviation for "light" can be "lt" or "lit."
Particle theory of light, proposed by Isaac Newton, views light as composed of discrete particles called photons. Wave theory of light, formulated by Thomas Young, describes light as a wave propagating through a medium. The wave theory better explains phenomena like interference and diffraction, while the particle theory accounts for aspects such as the photoelectric effect.
Historically, notable proponents of the theory of light have been scientists such as Isaac Newton, who proposed a corpuscular theory, and Thomas Young and Augustin-Jean Fresnel, who contributed to the development of the wave theory of light. More recently, Albert Einstein's work on the photoelectric effect helped establish the quantum theory of light.
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.
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".
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 One is the Newtonian physics theory, which is mostly correct but has been superseded by relativistic physics.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 most modern theory of light is the quantum theory.

The correct spelling is 'theory'.
By performing experiments whose goal is to prove that such theory is a mistaken theory.
Economic Theory
The quantum theory of light unifies the particle theory of light (photons) and wave theory of light by treating light as both particles and waves. Photons are quantized packets of energy that exhibit particle-like behavior, while light waves exhibit wave-like behavior with properties such as interference and diffraction. Quantum theory provides a framework to understand the dual nature of light.
That theory states that light behaves as group of particles.
