Neither. It is also not both. It's something else that so far we cannot describe with a single model.

It can be modelled as either.

I don't think we can really give a definitive answer with our current understanding.

It is commonly thought of as a particle that has wave properties.

Our understanding of light in physics is a model. It isn't both a particle or wave, but it displays characteristics that we attribute to both particles and waves (interference patterns, diffraction, polarisation as a wave and photoelectric effect as a particle). Until we find a better model to describe light and similar objects, we're stuck with it being both a particle and a wave.

That's what i though first because the idea of diffraction of light - supports light acting as waves because if the light was acting as a particle it would either just pass through the gap so the beam of light will be unchanged or would not pass through the gap at all.
But then the photoelectric affects provides evidence that light acts as a particle. since it has particle-like photons which provide energy.

so light is a particle and a wave.

I need to know this!
Light is considered to have the Wave-Particle Duality
It so acts like a wave at instances and as a particle at other time.

Hope this helps you....
Hit a Thumbs up if so.
