that light at times behaves like a particle and at other times like a wave
Explanation:
The fact that light can be characterized in terms of its wavelength and also having discrete quantity of energy suggests that light at times behaves like a particle and at other times like a wave.
This called the wave-particle nature of light or dual nature of light. It has been a bone of contention in the scientific world before the discovery of the photoelectric effect.
Light shows properties of waves as it can reflect, diffract, e.t.c and it shows properties of being a particle by having energetic photons.
