Wave-Particle Duality

[timothy_ho_4B]

Which experiments display the wave characteristics of a photon and which ones display the particle characteristics?

The photoelectric effect documents light's particle properties while de Broglie's wavelength hypothesis along with Davisson's and Germer's experiments showed light's wavelength properties. There are probably other experiments/theories/hypotheses that exist but these two are the ones we learned about. I hope this answer satisfies your question.
