Q. Show the Particle nature of light?
Particle nature of light One of the first main clues to the electron structure of atoms was Albert Einstein's explanation of the photoelectric effect a phenomenon in which electrons are ejected from the surface of a polished metal plate when it is struck by light.
Whether or not electrons are evicted depends on the frequency (colour) of the incident light. In 1905 Einstein articulate that this phenomenon could be explained only if light could act like a stream of particles that knocked electrons out of atoms. Particles or else photons of light at the high-frequency (violet) end of the visible spectrum had greater energy and were therefore more effective at dislodging electrons.
