Answer:
Newton's corpuscular theory.
Huygen's wave theory.
Maxwell's electro magnetic wave theory.
Planck's quantum theory.
Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein's light quantum theory is that light's energy is related to its oscillation frequency.
