Yes light is a particle or light shows a particle nature we cansee in the Quantum mechanics in which photos are described as energycarrier. Photons are basically an imaginary object that carry a certain amount of enery of specific thredhold frequency and the energy can be calculated by the product of frequency and plank constant since these Photons behaves like particles tht can claim that light is a particle.
Evidence: Photo Electric effect is a popular evidence and on other common evidence example is solar panels.
Reasoning : here photons from sunlight strikes the surface and they carry a sufficient amount of energy by striking to the surface they transfer their energy to the electrons which causes the ejection of the electron now these electrons are ready and free to move and moves towards the +ve direction which causes ultimately current.
