Explain particle-wave (dual) nature of matter.
Explain particle-wave (dual) nature of matter.
Optical phenomena like interference, diffraction and polarization can be explained by wave nature of light.
Photoelectric effect and Compton effect can be explained by particle nature of light.
Thus when light is in motion it behaves as wave. Its absorption and emission takes place in form of particle.
Thus light possess dual nature.
