How is light being described?
1.) as only a particle
2.) as neither a wave nor a particle
3.) as both a wave and a particle
4.) as only a wave

Light is described as both wave as well particle because light behave as wave in phenomenon like diffraction, interference, refraction, Doppler effect, etc whereas it behave as a particle in phenomenon like photoelectric effect, etc. Hope this helps.
