# Waves,Light, I need some help

Why do we think of light as a wave if in a vacume we still have light could it possibly be a bi product of multiple energie reacting on one another?

According to wave-particle duality theorem, in different situations light either acts as an EM wave or a photon particle. What exactly do you mean by "multiple energy reacting with each other" ?

I ment could it be that when any pure form of energy bent (rearanged) by another create light
