Ex FIITJEE and ALLEN FACULTY
Light is a form of energy. This much information is sufficient as far as classical physics is concerned.
But if one thinks from the quantum mechanical or modern physics perspective, then light does possess particle nature as prooved by Einstein's explanation of Photo-Electric effect.
Thanks!

Physics major at IIT-J researching in theoretical particle physics.
First, you need to understand that light exhibits dual nature ( particle-like as well as wave-like). The particle-like theories, such as on the experiments of the photoelectric effect and especially the Compton effect were solid proof of the fact that the Davisson and Germer experiment proved light exhibits either one of its nature in a particular experiment, then the de Broglie hypothesis on matter waves.
Planck's final formulation of the Blackbody Radiation and Heisenberg's uncertainty principle then led to the breakthrough for the start of new Quantum theory or Quantum Mechanics, where light could be studied as a wave function based on the legendary Schrödinger's Equation.
Anyways, light is a form of energy in both its natures.

Light has dual nature, both particle and wave, although it is energy.
In some experiments, like the photoelectric effect, it behaves as a particle called photons or quanta, which means a packet of energy.
Light behaves as a wave, reflection refraction etc. The wave only shows these phenomena.
