How can a photon be a wave and a particle?
The theory of light being a particle completely vanished until the end of the 19th century when Albert Einstein revived it. ... Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein's light quantum theory is that light's energy is related to its oscillation frequency.
How does a photon behave as a particle?
Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. They also found that increasing the intensity of light increased the number of electrons ejected, but not their speed. ...
