Light can be thought of an electromagnetic radiation which exhibits the property of a wave, particle or a ray?
All of these
Light is made up of packets, or chunks, of light which Einstein called them photons. The photons have energy and they vibrate. Light travels as particles and waves and both have been proven. the double slit experiment showed that light traveled as a wave but the photoelectric effect, as well as the Davisson-Germer experiment, showed light as a particle.
