Light is a Wave, Light is Photons

[Yolandia Winn 1A]

If light acts like both a wave and a series of photons, are there certain instances where it is acting like one or the other, or both? Do we know or can we predict such instances?

Light can't simultaneously be a pure wave and photon therefore there are not any instances where it acts as both.

[Yolandia Winn 1A]

My next question would then be, what instances is light acting as a series of photons vs merely a wave?

[604807557]

When light undergoes reflection, refraction, and diffraction it acts as a wave. When it packages its energy in small quanta it acts as a series of photons.
