How can it be said that light possesses wave nature?

(N/A) The wave nature of light is established by the following evidence:
$1$. Maxwell's equations for electromagnetism predicted that light is an electromagnetic wave consisting of oscillating electric and magnetic fields.
$2$. The experimental verification by Heinrich Hertz,who successfully produced and detected electromagnetic waves in the laboratory,confirmed that light behaves as an electromagnetic wave.
$3$. Phenomena such as interference,diffraction,and polarization,which are characteristic of wave motion,can only be explained by considering light as a wave.
