Photoelectric effect

Vedclass · Answer

(D) . Interference is a phenomenon in which two waves of the same frequency superpose to give a resultant intensity different from the sum of their separate intensities. Thus,it cannot exhibit the particle nature of light.$B$. Diffraction is a phenomenon in which light bends at the sharp edges of an obstacle or an aperture. Thus,it also cannot exhibit the particle nature of light.$C$. Polarisation of light is a property due to which a light ray,after emerging through a crystal (like tourmaline),has vibrations in a plane perpendicular to its direction of propagation. Thus,it also cannot explain the particle nature of light.$D$. The Photoelectric effect states that light travels in the form of bundles or packets of energy,called photons. This effect is explained on the basis of the quantum (particle) nature of light. Hence,it clearly explains the particle nature of light.Therefore,option $D$ is correct.

Which of the following phenomena exhibits the particle nature of light?
