The wave particle duality principle of quantum physics holds that light exhibit the behaviors of both waves and particles, depending upon the circumstances of the experiment.
 
The phenomena like interference, diffraction and polarisation of light could be explained satisfactorily by considering that light is of wave nature, while the phenomena of photoelectric effect and Compton effect were explained only by particle nature of light. It means light sometimes behaves as a wave and sometimes as a particle i.e. light has dual nature.
 
 
Light is an electromagnetic wave.
