electromagnetic wave behaves as particle---
This is demonstrated by the photoelectric effect. Light is shined on a piece of metal, causing electrons to be ejected. Classical theory said that E of ejected electron should increase with increase in light intensity---not observed. No ejected electrons are observed until light of high enough frequency. Number of electrons ejected depends on light intensity.
elecromagnetic wave behaves as wave --
when it reflects or bounces off of an obstacle. Light will also behave as a wave when it passes through another medium, causing refraction. Light that changes direction or diffracts will also behave as a wave.
