Classical physics considers light as a particle. It can explain properties of light like reflection, refraction, rectilinear propagation of light.

But when it comes to explaining diffraction and Polarisation phenomenon, it fails.

hence Max Plank came up with the idea of photon, that is a wave packet of energy in which the photon has a waveform. So they are satisfying discrete particle nature at macroscopic level and Light behaves as waves at microscopic levels.

Thus the dual nature of light. Further Schrödinger wave equation revolutionised physics. , Einstein gave a formula for photo electric effect using wave nature of light and got his Nobel prize.

This applies to "matter" particles as well, for example electrons, but basically any particle. The wave, in this case, specifies the probability of finding a photon (light particle), or some other particle, in a specific region.
