Quantum physics
Light diffracts when beamed through a slit.
The process off diffraction is one that belongs to waves.
Light can also cut as a particle from the photoelectric effect.
Particles such as electrons can be seen to out as waves when b

This effect occurs due to the electrons travelling past the atoms
If particles can be diffracted they must have a wavelengths (due

The photo electric effect proves that light can act as a particle.
