Diffraction of light is a phenomenon that demonstrates the wave nature of electromagnetic radiation.

Diffraction occurs when waves bend around obstacles or spread out through openings. This bending and spreading are characteristic wave behaviors.

Black-body radiation (explained by Planck) and the photoelectric effect (explained by Einstein) are phenomena that provided evidence for the particle nature of light (photons). Rutherford’s scattering experiment demonstrated the nuclear model of the atom, not the wave nature of light. Other phenomena demonstrating the wave nature of light include interference and polarization.
